Rat and termite proof high-heat-dissipation photovoltaic cable and preparation method thereof

Abstract

The invention discloses a rat and termite proof high-heat-dissipation photovoltaic cable and a preparation method thereof. The photovoltaic cable comprises a cable core, a low thermal resistance mineral filling material, a hot extrusion magnesium alloy cooling circular tube, a wrapping tape, a rat and termite proof protection layer and an outer protection layer, the cable core, the low thermal resistance mineral filling material, the hot extrusion magnesium alloy cooling circular tube, the wrapping tape, the rat and termite proof protection layer (an extrusion layer and a zinc plating fine round steel wire armor layer) and the outer protection layer are arranged in sequence from inside to outside, the cable core comprises a red insulation core and a black insulation core which are arrangedin parallel, and each insulation core is composed of a conductor layer and an insulation layer which is arranged on the outer side of the conductor layer. The cable has the excellent advantages of being low in smoke, free of toxicity, low in heat radiation, resistant to ultraviolet, environment, low temperature, dampness-heat and ageing and the like, the requirement of the cable that the servicelife is 30 years is met, the structure is flexible, the bending radius is small, and the laying requirements of various environments are met. The cable is especially suitable for occasions which are bad in environment and have the requirements of preventing rats and termites.

Description

technical field [0001] The invention relates to a cable and a preparation method thereof, in particular to a rodent-proof and high heat dissipation photovoltaic cable and a preparation method thereof. Background technique [0002] At present, most photovoltaic cables do not have anti-rodent and ant-proof performance, and some photovoltaic cables that meet the requirements of anti-rodent and ant are also mostly armored with steel tape or added anti-rodent and ant masterbatch to the sheath material, so as to meet the requirements of cable anti-rodent Ant performance. With the steel tape armoring method, the cable needs to increase the inner lining, which leads to an increase in the cost of the cable. When the flat cable is armored, it is also prone to leakage, and the bending radius of the steel tape armored cable is relatively large, which brings inconvenience to the construction and installation; The method of adding anti-rodent and ant masterbatch to the sheath material ha...

Problems solved by technology

With the steel tape armoring method, the cable needs to increase the inner lining, which leads to an increase in the cost of the cable. When the flat cable is armored, it is also prone to leakage, and the bending radius of the steel tape armored cable is relatively large, which brings inconvenience to the construction and installation; The method of adding anti-rodent and ant masterbatch to the sheath material has a strong irritating smell, which brings inconvenience to production and construction personnel, and the market is unwilling to accept this method of anti-rodent and ant

As we all know, the transmission of electric energy in the cable core will cause loss, which is mainly transformed into heat dissipation loss, which will not only make the transmission cable core heat and cause harm, but also greatly reduce the utilization rate of electric energy and the current carrying capacity of the cable.
