What's So Great About Cross Linked Polyethylene Insulated Cable?

The insulation materials of the cross linked polyethylene insulated cable

What is primarily good about the cross linked polyethylene insulated cable is the insulating materials. Insulation is defined as that the insulating materials are coated on the outside of conductors with different thicknesses according to the requirements of its voltage withstanding degree , which plays the role of isolating charged bodies from other parts. After the cable is electrified, the conductor will heat up. Therefore, the ideal type of insulation material should have good insulation performance and good thermal conductivity.

Cross linked polyethylene insulated cable uses chemical or physical methods to change the molecular structure of cable insulated polyethylene from linear molecular structure to main network molecular structure, that is, changed from thermoplastic polyethylene into thermosetting cross linked polyethylene, and thus greatly improves its heat resistance and mechanical properties, reduces its shrinkage, prevents it from melting after being heated, and maintains excellent electrical properties. Therefore, Cross linked polyethylene insulation has good advantages in heat resistance and mechanical properties, and has become an ideal insulation material at present.

The cross linked polyethylene insulated cable improves the performance of polyvinyl chloride insulated cable

The long-term working temperature of the polyvinyl chloride insulated cable is only 70℃, while the long-term allowable working temperature of the cross linked polyethylene insulated cable can reach 90℃. And the cross linked polyethylene insulated cable can maintain an elastic state at a temperature of 130℃. The insulation specific gravity of cross linked polyethylene is 0.92g/cm3. According to the standard, the thickness of the cross linked polyethylene insulation is allowed to be thinner than that of polyvinyl chloride insulation. Therefore, the cross linked polyethylene insulated cable is widely used because of their lighter weight, smaller diameter, convenient installation and laying, and simple fittings, in comparison with the polyvinyl chloride insulated cable.

The cross linked polyethylene insulated cable is widely recognized and applied by users in various fields because of its outstanding characteristics such as simple structure, light weight, no drop limit for laying, high allowable temperature, good heat resistance, large current carrying capacity, non-melting, chemical corrosion resistance and high mechanical strength.

What are the advantages of the cross linked polyethylene insulated cable?

The cross linked polyethylene insulated cable has excellent thermo-mechanical properties, excellent electrical properties and chemical corrosion resistance, and has the advantages of simple structure, light weight and unlimited laying. It is a new type of cable widely used in urban power grids, mines and factories at current society.

The cross linked polyethylene is a cross linked polyethylene whose linear molecular structure is transformed into three-dimensional network structure by chemical or physical means. To a great extent, it improves the thermo-mechanical properties of polyethylene and maintains excellent electrical properties.

The rated working temperature of the cross linked polyethylene insulated cable conductor can reach 90℃, which is higher than that of paper insulated cable, the polyvinyl chloride insulated cable and the polyethylene insulated cable, thus further improving the carrying capacity of which.
