Description
Technical field
The utility model relates to field of cable technology, specifically, more particularly to type solar photovoltaic cable easy to install.
Background technique
Currently, new energy, the photovoltaic power generation industry development of clean energy resource class are rapid, are maintaining the corollary system of photovoltaic products just
It often runs and be unable to do without electric energy conversion, based on solar power generation, whether the electric energy converted through solar energy is transmitted to
In electricity generation system, or between component each in electricity generation system electric energy is transmitted, be unable to do without cable.
The structure of photovoltaic cable seems simply, but for its working environment, and the moment is exposed under sunlight, can usually dislike
It is used under bad environmental condition, such as high temperature and ultraviolet radiation.The scene temperature that will lead to solar energy system when fine day is up to 100
DEG C, cable will directly influence the service life of whole system once damage under high temperature environment, or cause short circuit,
The appearance of the problems such as fire and dangerous personal injury.Compel so designing one kind and having with solar photovoltaic cable resistant to high temperature
The meaning cut.
Summary of the invention
To solve the above-mentioned problems, the utility model discloses a kind of type solar photovoltaic cables easy to install.
The utility model is achieved through the following technical solutions:
A kind of type solar photovoltaic cable easy to install, the cable include several conductors, and interior insulation is extruded outside the conductor
Layer constitutes insulated wire cores, extrudes external insulation layer after the insulated wire cores twisted synthesizing cable, the external insulation layer is externally provided with filled layer, institute
It states filled layer and is coated with thermal insulation layer, oversheath is extruded with outside the thermal insulation layer.
The inner insulating layer is extruded by heat curing type polyolefine material.
The external insulation layer is made of irradiation cross-linking flame-retardant polyolefine material.
The filled layer is glass-silk rope filled layer.
The thermal insulation layer is made of super glass wool.
The oversheath is that thermoplastics type is halogen-free and low-smoke flame-retardant polyolefin sheathed.
Compared with prior art, the utility model has the beneficial effects that
The utility model solar photovoltaic cable is using irradiation cross-linking flame-retardant polyolefine material as external insulation layer, weatherability
Energy and flame retardant property are good；Thermal insulation layer is arranged in the utility model, temperature when can guarantee solar photovoltaic cable exposure in the sun
Not too high rising, security performance are high.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
In figure: 1, conductor；2, inner insulating layer；3, external insulation layer；4, filled layer；5, thermal insulation layer；6, oversheath.
