Abstract

The invention provides a high-voltage direct-current polypropylene cable material. The high-voltage direct-current polypropylene cable material comprises the following components in parts by weight: 100 parts of a copolymerized modified polypropylene material and 0.5-1 part of an antioxidant. According to the high-voltage direct-current polypropylene cable material, co-polypropylene directly produced by a petrochemical device is adopted as an insulating material, the antioxidant is added, the high-voltage direct-current polypropylene cable material has excellent mechanical performance and electrical performance and can replace crosslinked polyethylene to serve as an insulating material of a high-voltage cable, and co-polypropylene is a thermoplastic material and is environmentally friendly; and the cable can be recycled after being decommissioned, so that the use cost of the cable material is reduced.

Description

technical field [0001] The invention relates to the technical field of power systems, in particular to a high-voltage DC polypropylene cable material and a preparation method thereof. Background technique [0002] XLPE (cross-linked polyethylene cable) has excellent mechanical and electrical properties, and is currently the main insulating material for extruded cables. However, since the by-products produced in the cross-linking process of cross-linked polyethylene are not easy to remove, it is difficult to control the purity of the cable, which will have a great impact on its breakdown performance and space charge performance. At the same time, the cross-linking and degassing process consumes a lot of energy, and the production efficiency is low. It is difficult to recycle the decommissioned insulating part, and the incineration or landfill causes great environmental pollution. Therefore, it is extremely important to develop an environmentally friendly cable that meets the...
