CAT6 manufacturers should pay attention to the purchase of power cord
CAT6 manufacturers to power cord is small, but the responsibility is great, not only directly related to the use of household appliances and life, more about the user's personal property safety, so consumers should not take it lightly when buying. However, the market has a wide variety of power cord products, each appliance has its own characteristics, the average consumer if not its method, it is easy to pick.
Power cord should be based on the different household appliances to buy
CAT6 manufacturers understand that different household appliances, the use of power cords are different. In general, lighting, recorders, TV sets with integrated plug line, it is appropriate to choose RVB-70, RVZ-70 parallel or twisted wire, its cross-sectional area should be within 0.75-1.0mm2; rice cookers, air conditioners, ventilating fans, electric fans, refrigerators, washing machines, etc. The power cord of the RVZ-70 type three-core wire with sheath is appropriate, and its cross-sectional area should be 0.75-1.5mm2; electric iron, about 100W solder electric chromium iron, hand drill and other mobile and heat source or spark electrical appliances and mobile sockets, to use RHF type line is appropriate, and its cross-sectional area should be 0.75-1.0mm2. When decorating houses, BV-70 type PVC insulated copper-core hard wire should be used for buried pipes, with a cross-sectional area of 1.0-2.0mm2 to ensure a long enough safe service life; as for mobile sockets used in wet environments such as kitchens and bathrooms, it is advisable to use RHF type wires. Socket connection, it is appropriate to use RVZ-70 type sheathed wire.
Power cord should be based on production certification and license number to purchase
CAT6 manufacturers reminded to buy wire, first look at the volume of the wire packaging with or without the China Electrical Products Certification Commission "Great Wall logo" and production license number; power cord should be based on the characteristics of the outer plastic skin to buy.
Wire outer plastic skin is bright, fine texture, lit with a lighter should be no open flame. Informal products using recycled plastic, dull color, loose texture, can ignite an open flame; secondly, look at the length, than the price, BVV2 × 2.5 The length of each volume is 100 ± 5 meters, the market price of about 280 yuan, informal products ranging from 60-80 meters in length, some manufacturers make the E insulation outer skin thick, so that the insiders also difficult to see the problem, you can generally count the The number of turns of wire, and then multiplied by the radius of the whole volume, you can roughly deduce the length, the price of such products between 100-130 yuan; then secondly, you can ask the merchant to cut a break to see the copper core material. 2 × 2.5 copper core diameter of 1.784 mm, available micrometer measurement, the regular product wire using fine red copper, the outer layer is bright and slightly soft, informal products copper Black and hard, a recycled copper, high resistivity, poor electrical conductivity, will heat up and unsafe; Finally, the purchase of wire should go to the electricity store or manufacturer's department.
