Problems solved by technology

[0002] At present, the production process of domestic cable insulation material manufacturers in the production of 10KV and 35KV XLPE can be found in figure 1 , if this method is used to produce 110KV grade XLPE, then obviously there are following problems: (1) the impurity content requirement of raw material can't be guaranteed; (2) transportation link increases impurity content; Seriously affect the electrical performance
However, large foreign companies use special ultra-clean PE (not currently available in China) when producing 110KV XLPE cable insulation materials, canned train transportation, canned storage, and pipeline transportation throughout the process. At present, domestic raw material manufacturers cannot meet this condition, so It is necessary to come up with a feasible method of producing 110KV class XLPE

Embodiment Construction

[0036] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments, but it is not intended to limit the present invention.

[0037] refer to figure 2 , a kind of production method of 110KV class XLPE cable insulating material of the present invention, it first mixes anti-oxidant and low-density high-pressure polyethylene, after carrying out certain process to it, then becomes liquid state when being heated to 40 ℃ and has been The filtered cross-linking agent dicumyl peroxide (DCP) is mixed according to the production process flow when producing 10KV and 35KV grade XLPE. The specific steps are:

[0038] (1) After weighing the particulate antioxidant A with a melting point of 150°C and the low-density high-pressure polyethylene (PE) B with a particle diameter of 2 mm, inject them into the mixing barrel 9, wherein the screw 25 mixes the two materials Uniform;

[0039] (2) The mixed material is melted ...
