1. Look at the label. The content of the wire certificate produced by a regular manufacturer should include: 3C certification mark, certification number, model specification, implementation standard, rated voltage, wire length, production date, producer, inspector, factory name, factory address...

Why choose TPEE as cable raw materialWhich material is used as the cable insulation material is determined by the use environment and demand of the cable, as well as the price and cost. For example, if a linear motor drag chain cable with a very high service life is made of PVC....

1 Structure and definitionThermocouple compensation wire is abbreviated as compensation wire, which is usually composed of compensation wire alloy wire, insulation layer, sheath, and shielding layer. Within a certain temperature range (including normal temperature), a pair of insulated wires ...

1. PVC materialCategory 6, PVC, with foil shield, 4 pairs twisted, 26AWGDefinition: It is based on polyvinyl chloride as the basic resin, adding stabilizers, plasticizers, calcium carbonate and other inorganic fillers, additives and lubricants and other additives, through mixing...

1. The characteristics of high temperature resistant cablesThe high temperature resistant cable is used for the connection line of the electrical instrument and the automatic control system of the AC rated voltage 450/750V and below. Compared with the ordinary cable, the high temperature resistant ...

Both flame-retardant cables and fire-resistant cables are commonly used cables, both of which are widely used in many industries. Although these two cables are commonly used in construction, the difference between them is still very big. Does the user have a specific understanding of distinguishing ...

In fact, there is no strict boundary between "wire" and "cable". Products with a small number of cores, small product diameter, and simple structure are usually called wires, those without insulation are called bare wires, and the others are called cables with larger conductor cross-sectional area.

1. Low resistivity: the resistivity of aluminum core cables is about 1.68 times higher than that of copper core cables. 2. Good ductility: the ductility of copper alloy is 20-40%, the ductility of electrical copper is more than 30%, while the ductility of aluminum alloy is only 18%....

1. Check whether the certificate of conformity, trademark, etc. on the appearance packaging are standard. It depends on whether there is 3C certification and quality system certification; whether the brand name, address, inspection stamp, and production date are printed on the trademark...

Theoretically speaking, the heat resistance of silicone rubber materials in the air is much better than that of organic rubber, and its usage is different at different temperatures. At 150°C, its physical and mechanical properties are basically not affected, and the compensation wire can ...
