Environmental-aging-resistant polyolefin photovoltaic cable

Abstract

The invention discloses an environmental-aging-resistant polyolefin photovoltaic cable, comprising a polyolefin jacket; a polytetrafluoroethylene layer is fixedly installed on the outer surface of thepolyolefin jacket; a high-temperature-resistant braided cover is fixedly installed on the inner surface of the polyolefin jacket; an insulating protective cover is fixedly installed on the inner surface of the high-temperature-resistant braided cover; a support shaping steel wire is installed on the outer surface of the insulating protective cover in a winding way; five groups of copper core insulating sleeves are fixedly installed on the inner surface of the insulating protective cover. The environmental-aging-resistant polyolefin photovoltaic cable provided by the invention is provided withthe polytetrafluoroethylene layer, the high-temperature-resistant braided cover and the support shaping steel wire, thus being better in environmental aging resistance, and prolonging the service life; high-temperature-resistant protection can be realized, aging caused by the overhigh temperature of the internal insulating protective cover is prevented, and the cable can be protected by supporting and shaping, so that the structural strength of the whole cable is improved; therefore, the environmental-aging-resistant polyolefin photovoltaic cable has certain practicability and brings a betteruse prospect.

Description

technical field [0001] The invention relates to the field of photovoltaic cables, in particular to an anti-environment aging polyolefin photovoltaic cable. Background technique [0002] Polyolefin photovoltaic cables are cables used to transmit electric energy in photovoltaic power generation. They are widely used in power plants and photovoltaic power plants, etc., and have good use effects. The existing polyolefin photovoltaic cables cannot meet people's needs, so there is a need for More convenient polyolefin photovoltaic cables; the existing polyolefin photovoltaic cables have certain disadvantages in use. First, the effect of anti-environmental aging is not ideal, which reduces the service life for a long time. Secondly, the effect of high temperature resistance is poor. It can protect the inner insulating layer against high temperature, and finally, it cannot be protected by support and shaping, which reduces the overall structural strength of the cable. Therefore, we ...
