Fire resistance refers to the ability to maintain a certain period of time under the condition of flame burning, that is, to maintain the integrity of the circuit. This type of cable has a certain period of power supply capacity in the flame.Fire-resistant cables can be divided into two grades accor... READ MORE
One of the main differences between flexible mineral cables and other ordinary cables is that high-energy electron beams (β rays) generated by high-power electron accelerators are used to cross-link specially formulated inorganic compounds, so that the flexible mineral cables can withstand The worki...

1. External force damage. Judging from the operation analysis in recent years, especially in Pudong, Shanghai, where the economy is developing rapidly, there are quite a lot of cable faults. All obstacles are caused by mechanical damage.2. The insulation is damp. This situation is also very common, ... READ MORE
Wires and cables used to directly transmit electrical energy from the power distribution point of the power system to various electrical equipment and appliances. Such as: wires and cables for electrical connections and control signals in various industrial and agricultural equipment. This typ... READ MORE
Commonly used cable classification 1. Wire and bare inner conductor products refers to only conductors without insulating layers and other structures. Such as: copper, aluminum and various composite metal single wires; various structures of overhead transmission stranded wires, flexible wiring,... READ MORE
Copper wires and hard wires generally refer to home improvement wires, so they are often worried when buying interior decoration, but everyone can rest assured that the quality of the cable has nothing to do with the hardness and softness, mainly the raw materials and production process of the prod...

1. Hard wire and soft wire The core of the hard wire is relatively thick, the general type is BV, which is relatively resistant to short-circuit current and easy to form, but it is difficult to wear the tube, especially the cable of 2.5 square meters or more. The flexible cord is composed of cable... READ MORE
