Cross-linking cable

Cross-linked cable is the abbreviation of cross-linked polyethylene insulated cable. Cross-linked cable is suitable for power transmission and distribution lines with power frequency AC voltage of 500KV and below. At present, most high-voltage cables use cross-linked polyethylene insulation.

Cross-linked polyethylene is a cross-linked polyethylene that uses chemical or physical methods to transform linear molecular structure polyethylene into a three-dimensional network structure, thereby greatly improving the thermo-mechanical properties of polyethylene and maintaining excellent Electrical performance.

UV cross-linking machine advantages

The new type of LED UV-irradiated polyolefin cross-linking equipment adopts new technology:

 1. The power consumption of LED lamps is 70% less than that of the old type.

 2. The cross-linking speed is more than twice the original.

 3. Solving the shortcomings of thick insulation.

 4. Less land occupation.

 5. Greatly improving production efficiency. Only small modification on present extrusion production line before take up to accomplish online cross-linking process. 

Process flow summery

The process flow of the UV light irradiated cable cross-linking equipment is to use ultraviolet light as the radiation source, extruding the mixed light-crosslinked polyolefin ingredients on the conductive wire core, and then immediately enter the special irradiation equipment to do light crosslinking in molten state. Then after cooling treatments at different temperatures and other subsequent processing to obtain photo-crosslinked polyolefin insulated wire and cable products.

The UV-irradiated cable cross-linking equipment only needs to be slightly modified on the original ordinary extrusion production line. By adding the upper traction, irradiation box, and electrical control cabinet in a small area to meet the use requirements to produce UV radiation cross-linked polyethylene wire and cable products.
