Problems solved by technology

[0002] At present, the production process flow of domestic cable insulation material manufacturers in the production of 10kV and 35kV XLPE is shown in Figure 1. If this method is used to produce 110kV XLPE, the following problems obviously exist: (1) The impurity content of raw materials The requirements cannot be guaranteed; (2) The impurity content is increased in the transportation process; (3) The antioxidant cannot be fully melted, which seriously affects the electrical properties
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 viable 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 not as a limitation of the present invention.

[0037] Referring to Fig. 2, a production method of a 110kV class XLPE cable insulation material of the present invention, it first mixes an antioxidant with a low-density high-pressure polyethylene, and after a certain process is carried out on it, it becomes liquid when heated to 40°C State and filtered cross-linking agent dicumyl peroxide (DCP) mixed, according to the production process when producing 10kV and 35kV grade XLPE, get final product. The specific steps are:

[0038] (1) After the melting point is 150 DEG C of particulate antioxidant A and the low-density high-pressure polyethylene (PE) B with a diameter of 2 mm, they are injected into the first mixing barrel 9, wherein the first screw 25 Mix the two materials evenly;

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

Abstract

This invention discloses a 110 KV XLPE cable isolation material production method, which comprises the following steps: first to mix the anti-oxygen agent and high pressure polyethene for certain process; then to mix them with the filtered liquid cross linker of dicumyl peroxide under forth degrees; to product as the one in 10 KV and 35 KV to finish the process.

Description

technical field [0001] The invention relates to a production method of a cable material, in particular to a production method of a 110kV class XLPE cable insulation material, belonging to the field of new material processing. Background technique [0002] At present, the production process flow of domestic cable insulation material manufacturers in the production of 10kV and 35kV XLPE is shown in Figure 1. If this method is used to produce 110kV XLPE, the following problems obviously exist: (1) The impurity content of raw materials The requirements cannot be guaranteed; (2) The impurity content is increased in the transportation link; (3) The antioxidant cannot be fully melted, which seriously affects the electrical properties. 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 pr...
