To know what cross section area of the cable should be prepare for a household, we have to know the its maximum electricity demand cable`s max. current carrying capacity. Current house-service entrance wire generally is 4mm².Therefore, the total amps of household appliances turned on at the same time are should not exceed 25A,which means it ups to 5500w. Some electrical appliances cost more electricity consumption than others. See as follows: 3 sets Air Conditioner:3000w(estimate14A) Water Heater:10A Micro-Oven:4A Electric Rice Cooker:4A Dish-Washer:8A Washing Machine with dryer:10A Electric Switches:4A Notel: Among fire caused by electrical power,90% is because of joint heat. So all joints need to bewelded. If not,they must be replaced in 5-10years. For national standard, theoretical long-term working current please see below two as reference: 4mm²:25-32A(max power is 8000w) 6 mm²:32-40A(max power is 9000w) To a household cable choice, we should take total power of all appliances into consideration. To get the suitable cable wire,we should also know its ma. Current capacity. The calculation to get its current carry capacity should base on below equation:I= w/uxk IMax. Line Capacitance,its Unit is A WTotal Domestic Electrical Power,its unit is w URated Voltage,Unit is V kSafety Index of Overvoltage,common range is from 1.2 to 1.3 You could calculate the max required electricity in total based on above equation. Then you could also know best option according to max. current capacity of each cross section area cable: 1.P is for Total load of the circuit,also known as total electrical power of endmost terminal set. The unit is KW. 2.U is for Voltage range,U0/U 220/380V. 3.Total current of the circuit, we call it I,I=P/U, its unit is A 4.cable type decision make(copper conductor/aluminum,single core/multicore) 5. X is for current capacity. 6.cross section area=IX

When fire happens, it can not only retard the flame but also stop potential fires spread and disaster expansion. 2.No Halogen Eco-friendly material used in its insulation and sheath with oxidation-barrier ensure this cable the high electrical performance, physical and mechanical properties. Those material also guarantee non-halogen component ,which solve the secondary pollution under fire condition and avoid any release of cancer-causing gas like TCDD. 3.Low Halogen Its insulation and sheath do not contain any heavy metal like Plumbum or Cadmium which harm people`s health. Therefore there will not cause any pollution to oil and water while daily using and disposal treatment. 4.No corrosion gas will be produce No harm material use make sure there will not produce any toxic gas like HC while cable production, application or combustion. There will hardly ever cause acid gas, that will protect people, equipments and devices. 5.High Light Transmittance The smoke released by eco-friendly cable under fire is rare and thin which is beneficial to people evacuation and fire extinction. Generally speaking, the light transmittance rate of eco-friendly cable is over 40%,that is higher a lot than other traditional flame retardant cable with 20% rate. 6.High resistant to UV and water This performance ensure the cable not easily weather-worn. To some extent,it can slow down aging process and extent life use time. In conclusion, eco-friendly cable is becoming a trend. It is potentially for this product to grow up to market mainstream in the future.

Recently, our company is developing a new production of mineral insulated fireproof power cable, and its test runs were passed under the supervision and inspection of our own and invited electrical technicians and engineers. People rely more and more on fire and are more and more endangered by fire in modern society. Therefore, the fire safety control of building materials, including integrated wiring systems has become a concern. Outside fire will destroy the building wiring system, causing power breakdown or short circuit; Meanwhile, the wiring system in the flame will not only release harmful gases but also may feed the fire gradually spread to other floors or other rooms. As we know, most deaths caused by the fires were caused by poisonous gases produced under fire situation, suffocated by expanded fumes in invisible paths. So fire control has become one of the key considerations of power system performance. Mineral insulated cable will satisfy this high fire protection requirements for its various good performance. --Excellent flame retardant and fire resistant performance --High overload protection strength --Large current carrying capacity --High working temperature --Waterproof, corrosion resistant, explosion resistant --Long lifetime use --Smaller outer diameter, lighter weight --High mechanical strength --Good bending property --Good earthing performance

A.What is the difference? Literally Speaking, Each wire of cable is thick and single solid, could also named as hard core wiring cable. However, wires in multi-stranded type is thin and multiple, also could named as soft cable/flexible cable. Please also see below picture for your reference. B.Which is more suitable for decorating houses. a.In construction:multi-stranded wiring cable is better As single solid wiring cable consists of one thick copper wire, it is relatively stronger and harder so that it will be more difficult for threading process. b.Thermal Dissipation:multi-stranded wiring cable is better It is made of multiple fine copper wire, and there have enough space among these copper wires to get a better heat dissipation. c.Easily oxidized or not: Single solid wiring cable is not easy to get oxidized. For long-term use, partial copper wires in multi-stranded wiring cable will get oxidized and broke, which will reduce its cross-sectional area and lead to a higher safety risk. Single solid type does not have space inside,only its surface get oxidized, so it lives longer lifetime. d.Price:single solid wiring cable is with lower price. It requires more procedures to produce multi-stranded wiring cable, that is why. In conclusion,single solid wiring cable is the winner for its usage,if you are the house owner, we recommend you choose this type. And multi-stranded wiring cable is the winner for its installation convenience, installation technician prefer to choose this type.

There are thousands of manufacturers and enterprises of electrical cable wire all around the world and they are of variable quality. It is very complicated to buyers to decide a good quality product. Please see below five ways to identify electrical cable and wire for your reference: 1.To see a. to see if it is with certification of quality system b. to see if all the certification fit the standard or not. c. to see if there print the marking of factory name, factory address, hallmark, badge, date of manufacture d. To see if there have print product detail on the cable or wire such as trade mark,specification, voltage and so on. 2.To Touch we must try first hand the desirability of a wire bent repeatedly any soft anti-fatigue and plastic or rubber flexible handle and wire insulation is no cracks in high-class product. 3.To identify the copper Generally, the qualified copper conductor should be pure,glossy and soft. However, poor quality copper cable wire`s conductor is more darker, yellowish or white-ish,and contains many impurities, it is also shows a worse mechanical strength and resilience which makes this cable wire breaks with little force. While inspection, only need to strip off 2 cm from the cable head and rub it with a white paper, if there have any dirt on that paper,that indicates the conductor of this cable contains many impurities. 4.To check the weight good quality electrical cable and wire always within weight standard, please see below some data for your reference. Under normal circumstances, the weight range of 1.5mm² single core electrical copper cable is from 1.8kg to 1.9kg each 100 meters; and the weight range of same type 2.5mm2 cable wire is from 3kg to 3.1kg; for 4.0mm2 that will be from 4 to 4.6kg. Therefore, a poor quality cable or wire is with insufficient weight, or less length, or to many impurities. 5.To compare the price Due to low cost of manufacturing poor quality electrical cable wire, some enterprises tend to lure customers with cheap and fine ads. But the only truth is on its low price. Therefore, it is very important to handle well between price and quality to reduce any potential risks.

Generally speaking, the conductor of electrical wires among worldwide market is copper and aluminum. But how to make a decision between them if we are inquiring electrical wires for household installation and appliances? That is quite important. So we must know what is the distinction between them: 1. Load Power Rating With same cross section area, copper conductor electrical insulated wire gets a higher load power rating than aluminum type. Let me make an example without actual calculation just for your reference: If 2.5mm² aluminum electrical insulated wire can load 2500V,then copper can load 3000V. 2. Flexibility Copper electrical insulated wire is with better flexibility. It can be bend easily. Aluminum type is more possible to break off if we bend it. 3. Stability Aluminum electrical insulated wire is prone to oxidation, thus changing into bigger resistivity and lowing its rating of power loading. It is big potential safety risk not only for property but for human life. Copper conductor type is with excellent stability. 4. Resistivity The electrical resistivity of aluminum conductor type is 1.68 times higher than copper conductor type, which is bad for utilization rate of electricity because of its higher power loss and heat emission. 5. Price Aluminum wire is much cheaper and lighter than copper wire and Advice: For long-term finance and safety consideration,please be sure to choose copper conductor electrical insulated wire but not aluminum conductor type. Please do not dig groove in the wall to bury the wire for installation. It is highly recommend to use a regular pre-buried sleeve installation to avoid electric leakage and fire risk.
