Teach you how to choose a power cord

At present, there are various styles of power cord products on the entire market, and each electrical product has its own characteristics. Therefore, many people still do not understand when choosing power cords. Although power cords are small, they are of great importance, not only directly related to the adoption, use and duration of electrical products, but also to our personal electrical safety. Therefore, consumers must not take it lightly when identifying them.

The power cord should be selected according to different household appliances. Different household appliances use different power cords. Generally speaking, for integrated plug cables used in lighting fixtures, recorders, and televisions, RVB-70 and RVZ-70 parallel or twisted pair cables should be selected, with a cross-sectional area within the range of 0.75-1.0mm2; The power cords for rice cookers, air conditioners, ventilation fans, electric fans, refrigerators, washing machines, etc. should use RVZ-70 three core sheathed wires with a cross-sectional area of 0.75-1.5mm2; Electrical appliances and mobile sockets such as electric irons, 100W soldering chrome iron, and hand drills that are highly mobile and have heat sources or electric sparks should use RHF type wires with a cross-sectional area of 0.75-1.0mm2.

When decorating a house, BV-70 PVC insulated copper core hard wire should be used for buried pipes and concealed wires, with a cross-sectional area of about 1.0-2.0mm to ensure a sufficiently long safe service life; For mobile socket connections used in damp environments such as kitchens and bathrooms, it is recommended to use RVZ-70 shielded wires. When purchasing wires, check if the outer plastic skin of the wire has a bright color and fine texture. When igniting with a lighter, there should be no open flame.
