Environment-friendly DC 1500V mouse-proof and anti-termite cable used for photovoltaic power generation system

Abstract

The invention discloses an environment-friendly DC 1500V mouse-proof and anti-termite cable used for a photovoltaic power generation system. The cable comprises a cable body which comprises two cable units. The two cable units are symmetrically arranged. Each cable unit comprises copper conductor wire cores, an irradiation crosslinked flame-retardant polyolefin insulating layer, a flame-retardant tape layer, an oxygen insulation layer and an irradiation crosslinked flame-retardant polyolefin external sheath which are arranged from inside to outside in turn. The two cable units are connected into an integrated structure through the irradiation crosslinked mouse-proof and anti-termite flame-retardant polyolefin external sheath. The material structure of the high-temperature-resistant 150 DEG C irradiation crosslinked flame-retardant polyolefin insulating layer and the high-temperature-resistant 150 DEG C irradiation crosslinked mouse-proof and anti-termite flame-retardant polyolefin external sheath is adopted so that the cable has the cold-resistant, heat-resistant, ultraviolet-resistant, ozone-resistant and mouse-proof and anti-termite characteristics and has high mechanical strength and acid and alkali resistance, moisture and heat resistance and halogen-free, low-smoke and flame-retardant performance and thus the demands of the market and the customers can be fully met.

Description

technical field [0001] The invention relates to the field of power cables, in particular to an environment-friendly DC 1500V rodent-proof cable for a photovoltaic power generation system. Background technique [0002] With the rapid development of the national economy, power cables are used in various aspects of industry and power systems. Among them, power stations have relatively high requirements for cables. At present, mainstream power station designs and products such as photovoltaic modules, inverters, combiner boxes, and cables are all Designed and manufactured based on the voltage requirement of 1000V at the DC terminal. Photovoltaic power plants need to reduce costs and increase efficiency. Raising the voltage is one of the effective measures to reduce line loss. The subsequent 1500V voltage level has attracted the attention and pursuit of users. Under the 1500V voltage level, the power station can reduce the cost of supervision , the number of module strings, cabl...

Photovoltaic power plants need to reduce costs and increase efficiency. Raising the voltage is one of the effective measures to reduce line loss. The subsequent 1500V voltage level has attracted the attention and pursuit of users. Under the 1500V voltage level, the power station can reduce the cost of supervision , the number of module strings, cables, and combiner boxes has been reduced. At present, a large number of DC cables in photovoltaic power plants need to be laid outdoors. The environmental conditions are harsh, the overall performance is poor, and the mechanical strength is not enough. Hazards such as fire caused by short circuit accident
