Introduction to irradiation and silane crosslinking cable difference

Customer orders are sometimes encountered model for WDZ - YJ (F) E flexible cables, this kind of cable should be interpreted as the name of the copper core irradiation crosslinking polyethylene insulation, low smoke zero halogen flame retardant polyolefin sheathed power cable, power cable product standards GB/T 12706.1 ~ 3-2008 of the rated voltage 1 kV to 35 kV (Um = 1.2 kV) = 40.5 kV (Um) squeeze, insulated power cables and accessories, the first part of appendix D "the cable products of the clause," said about insulation code method, for crosslinked polyethylene insulation, code-named YJ, did not distinguish between what crosslinking type (physical or chemical), belongs to physical crosslinking type irradiation crosslinking, and combined with "F" in the model, the industry said an idiomatic irradiation crosslinking insulation methods.Standards should be still for GB/T 12706-12706.

Customers use this model to use irradiation crosslinking insulation wire core to meet the requirements of the use of the special occasions.The irradiation crosslinking and ordinary silane insulation what are the advantages?Irradiation crosslinking is using high energy electron beam produced by the electron accelerator to the crosslinking of cable, the cable insulation layer of polyethylene structure.

By linear molecules into a three-dimensional network structure, formed less than the three dimensional lattice water molecules, the polyethylene surface and internal form dense layer, thus effectively prevent the hydroxyl and the combination of water molecules, the crosslinking method not only improves the heat resistance, abrasion resistance and flame retardant performance of wire and cable, of the block water. The crosslinking way no heat, no water, can make PE crosslinking, and can improve the flame retardant and electrical cable wire performance of cable.Make the cable has low smoke, halogen-free, flame retardant and high temperature resistant characteristics.
