Problems solved by technology

Traditional photovoltaic cables can no longer meet the existing complex use environment. When photovoltaic cables are used outdoors, they are often eaten by mice and termites, which affects the performance of photovoltaic cables to varying degrees.
If the sheath is damaged, the sheath cannot protect the insulation
Can not play the role of sunlight resistance, acid and alkali resistance, ozone resistance, etc.
What's more serious is that the copper wire is exposed, which will have a serious impact on the entire photovoltaic system

Embodiment Construction

[0013] The present invention will be further described below in conjunction with the embodiments in the drawings:

[0014] Such as figure 1 As shown, the present invention mainly includes conductor 1, insulating layer 2, middle layer 3, steel wire armor layer 4, sheath layer 5 and outer sheath 6. The outer surface of conductor 1 is covered with insulating layer 2, and conductor 1 generally uses 4mm2 Specifications. The insulating layer 2 is made of XLPE (cross-linked polyethylene) material, and the insulating layer 2 ensures the voltage resistance and insulation performance of the photovoltaic cable in use.

[0015] The outer surface of the insulating layer 2 is covered with an intermediate layer 3, which is made of XLPE (cross-linked polyethylene) material. The intermediate layer 3 protects the insulating layer 2 from external force damage and improves the physical strength of the photovoltaic cable.

[0016] The outer surface of the middle layer 3 is covered with a steel wire arm...

Abstract

The invention belongs to the technical field of photovoltaic cables, and relates to a photovoltaic cable, in particular to a high strength photovoltaic cable preventing biting of rats and ants. The photovoltaic cable comprises a conductor, an insulation layer, a middle covering layer, a steel wire armoring layer, a sheath layer and an outer protecting layer. The middle covering layer wraps the outer surface of the insulation layer, the steel wire armoring layer wraps the outer surface of the middle covering layer, the sheath layer wraps the outer surface of the steel wire armoring layer, and the outer protecting layer wraps the outer surface of the sheath layer. The photovoltaic cable preventing rats and ants is simple, compact and reasonable in structure, expands the range of use environments, not only can be used outdoors, but also can be used under special environments, reinforces physical strength, avoids damage caused by biting of the rats and the ants, and meanwhile improves anti-low-frequency-interference capacity to a certain degree.

Description

Technical field [0001] The invention relates to a photovoltaic cable, in particular to a high-strength photovoltaic cable resistant to rat and ant bites, and belongs to the technical field of photovoltaic cables. Background technique [0002] At present, the photovoltaic cables on the market are single-core double-insulated cables. The double-insulation materials are all XLPE (cross-linked polyethylene) materials. The rated voltage is 600Vac, 1800Vdc, and the rated temperature is -40℃ to 120℃. It is used to connect solar cells. The solar cell box in the panel is used to transmit electrical energy. It can only be used in a specific environment to guarantee its 25-year service life. With the development of the global photovoltaic industry, photovoltaic cables have now entered thousands of households, and photovoltaic cables have been applied in various fields. Traditional photovoltaic cables can no longer meet the existing complex use environment. When photovoltaic cables are use...
