Conductor shielding:
According to relevant industry standards, cables with rated voltage exceeding 2KV need conductor shielding. Conductor shielding, also known as inner shielding, is used to form a smooth layer on the relatively rough surface of the stranded conductor to reduce the concentration of electric field at the insulation interface.
Copper-clad aluminum wire can be divided into two categories: one is the copper-clad aluminum wire used for signaling or communication. The other type is the copper-clad aluminum wire used for the power supply.
Bare Conductor Wire
Bare wire and bare conductor products refer to the conductive wire without insulation and sheath. It mainly includes three series of products: bare single wire, bare stranded wire and profile wire.
Copper and aluminum single wire: including soft copper single wire, hard copper single wire, soft aluminum single wire, hard aluminum single wire. Mainly used as a variety of wire and cable semi-products, a small amount of communication wire and motor appliances manufacturing.
Generally, power cables are within 5 cores. They are generally used for high-voltage power. The number of cores of control cables is relatively large. Sometimes customer requirements are different, generally to 37 cores, but there are more cores.
The following description is for the 10kV power cable.
The outermost layer of the 11kv power cable is generally rubber or rubber composite sheath. The function of this layer is firstly to insulate, but also to protect the cable from damage.
Power cables are divided into high voltage and low voltage cables. If it is high voltage, there will be a layer of resin-like filler inside, which serves as insulation. In high-voltage cables, this layer is the most important part of the insulation. The low voltage does not have this layer, and then there will be something like a ribbon wrapped inside, which is to fix each core of the cable and fill the gap in the middle.
Electric cables are mainly used to transmit electricity. It consists of one or more mutually insulated conductors. At present, most of the insulation in the electrical power system is made of PVC, XLPE, and LSZH materials.
ZMS Cable supplied the 33/66kV Power cable to the Philippines local EPC construction company, which was used for the power transmission line replacement work.
With the spread of new coronaviruses around the world, safety prevention and control are particularly important in this increasingly severe situation. We have taken several approaches to this disease. ZMS has made a real contribution to the fight against the new coronaviruses.
