PVC granulator
Formulation: Cross-linked cable usually means that the insulation layer of the cable is made of cross-linked material. The most commonly used material is cross-linked polyethylene. The cross-linking process is to process the polyethylene material with a linear molecular structure through a specific processing method to form a cross-linked polyethylene with a network-like branching structure. The long-term allowable working charge is increased from
to
(
or higher
)
, and the short-circuit allowable temperature is increased from
to
(< br/>or higher
)
, while maintaining its original excellent electrical performance, it greatly improves the actual performance. At present, the technological methods for producing cross-linked cables in the cable industry are divided into three categories: the first type of peroxide chemical cross-linking, including saturated vapor cross-linking, inert gas cross-linking, molten salt cross-linking, and silicone oil cross-linking. The third type is used in China. Two types are dry chemical cross-linking and inert gas cross-linking
--
Dry chemical cross-linking uses polyethylene insulation material added with peroxy compound cross-linking agent, and the conductor shielding layer is completed through three-layer co-extrusion

Insulating layer
――
After extrusion of the insulating shielding layer, the cross-linking process is completed continuously and evenly through a sealed cross-linking tube filled with high-temperature and high-pressure nitrogen. The heat transfer medium is nitrogen

. The cross-linked polyethylene has excellent electrical properties and the production range can reach
