At present, the insulation materials used in cable production are roughly divided into PE, PVC, and XLPE. The following ZMS cable editor will introduce the difference between each PE, PVC, and XLPE, the insulation materials used in cables. Cable insulation classification and characteristicsPVCPolyvinyl chloride is a polymer made by the free po...
The reasons for the sharp increase in water bills in many parts of FranceThe price of electricity and raw materials has already had an impact on the cost of water, from January 1, 2023, the cost of water in France will rise sharply, and in some areas may be close to 20% of the original increase. Electricity and raw materials, although not often contacted i...
XLPE insulated power cable not only has excellent electrical performance, mechanical properties, heat aging resistance, environmental stress resistance and chemical corrosion resistance, but also has a simple structure, easy to use, and is not limited by the installation drop. High temperature (90o), large transmission capacity and so on.
Can be laid indoors, tunnels, cable trenches, pipelines, flammable and severely corroded, but can not withstand mechanical external forces. It is necessary to bear the external force of the machine and add the steel tape armor.
However, due to the particularity of the cable, there are special requirements for the installation, operation and maintenance of the cable.Cable dampness or water ingress reduces the insulation resistance of the cable, which is an important aspect of the cable line running accident.
Difference Between Steel Belt Armoring and Chain Armoring of Aluminum Alloy CableArmored cables are assembled from different material conductors in metal sleeves with insulating materials and are processed into a flexible, solid assembly. Steel tape armor is used only for buried cables or ordinary pipes, general ground, tunnels, etc. Laying. ...
The cables are designed for distribution of electrical power with nominal voltage Uo/U ranging from 3.6/6.6KV to 19/33KV and frequency 50Hz.
They are suitable for installation mostly in power supply stations, indoors and in cable ducts, outdoors, underground and in water as well as for installation on cable trays for industries, switchboards and power stations.
Technical Difficulties of Submarine CablesSubmarine cables are cables laid at the bottom of rivers, lakes and sea. They have a history of more than one hundred years. They were originally used for power supply to offshore lighthouses and other equipment. Now submarine cables are mainly used for connecting islands to the mainland or i...
The Difference between EPR and FR-XLPE CablesCables and wires are used for the transmission of electricity, magnetism, information and conversion of electromagnetic energy. Broadly defined wires and cables as cables. The general low voltage cable structure : Conductor -> Insulation -> Inner Jacket -> Outer Jacket. Because of the requir...
Application of Cross-Linked Polyethylene Insulation MaterialsCables can be divided into bare wires, insulated wires, heat-resistant wires, shielded wires, power cables, control cables, communication cables, and RF cables.
Commonly Insulated Wires are the Following: PVC insulated wire, PVC insulated cord, nitrile PVC insulatio...
