Abstract

The invention belongs to the field of power cables and particularly relates to an anti-corrosion flame-retardant wind power cable sheath, an insulating material and a preparation method of the sheath and the insulating material. The inner layer insulating material is prepared from, by weight, 40-60 parts of EPDM, 10-25 parts of polyvinyl chloride, 5-10 parts of paraffin oil, 5-15 parts of calcium carbonate, 30-60 parts of kaoline, 1-3 parts of anti-ageing agent, 1-3 parts of assistant crosslinker, 0.5-2 parts of vulcanizing agent and 1.5-3.5 parts of flame-retardant agent. The outer layer sheath material is prepared from, by weight, 40-60 parts of ethylene propylene terpolymer A, 35-60 parts of ethylene propylene terpolymer B, 3-8 parts of activating agent, 2-4 parts of stabilizer, 2-4 parts of antioxidant, 2-4 parts of cold-resistant plasticizer, 1-3 parts of silane coupling agent, 5-10 parts of compound vulcanizing agent, 3-8 parts of flame-retardant agent and 30-50 parts of filling agent. Process improvement is conducted on the inner layer insulting material and the outer layer sheath material of a wind power cable, the cable can be used in the environment of -40-100 DEG C for a long time, the cable has good softness, oil resistance, cold resistance, abrasion resistance, acid and alkali resistance, flame retardancy and the like, and the requirement that a draught fan safely and normally runs in the changeable and severe weather environment is met.

Description

technical field [0001] The invention belongs to the field of power cables, and in particular relates to an anti-corrosion and flame-retardant wind energy cable sheath and insulating material and a preparation method thereof. Background technique [0002] In recent years, with the adjustment of the national industrial policy and the sustained and rapid development of the real economy, especially the further strengthening of the state's environmental protection supervision and the gradual phase-out of small coal-fired units, it is imperative to vigorously develop new energy power. Wind power is a preferred new energy source, and wind energy cables are mainly used for the connection and output lines of wind turbines. Therefore, in view of the complex factors such as the environment and climate around wind power generation, high-quality wind power cables must not only be wear-resistant, cold-resistant, aging-resistant, and weather-resistant, but also have the characteristics of ...
