Description
Technical field
The present invention relates to field of cable technology, and in particular to a kind of novel photovoltaic cable.
Background technique
It is well known that heliotechnics will become following one of the green energy resource technology, solar energy or photovoltaic (PV) are in
State's application is increasingly extensive, and in addition to the photovoltaic power generation factory of governmental support quickly grows, private investor is also just actively founding the factory, the sun
The sale of energy component will be all over the world, builds the profitability photovoltaic power generation factory of economical and efficient, represents all solar energy manufactures
The most important target of quotient and core competitiveness.In fact, profitability depend not only on solar components itself efficiency or
High-performance naturally also be unable to do without the photovoltaic or solar energy private cable of transmission electric energy, and high quality cable can be to avoid because high
Maintenance and maintenance cost and cause solar energy system that can not get a profit, will but if failing the private cable using application of solar energy
Influence whether the service life of whole system, and in fact, solar energy system can usually use in harsh environments, in addition to
Except in the case of high temperature and ultraviolet radiation, mechanical load is also often born, during installation and maintenance, cable can be in roof structure
Sharp edge on be routed, while cable must bear pressure, bending, tension, be stretched across load and brute force attack, if cable itself
Intensity is inadequate, then cable will seriously damaged or even conductor broken string cause open circuit, to influence the peace of entire photovoltaic system
It entirely uses, or leads to short circuit, fire and the dangerous appearance of personal injury.
Photovoltaic cable currently on the market is all single-core cable, also as the continuous development of science and technology, the big continuous increasing of dosage
Add, single-core cable has been not suitable with the requirement for producing and living now, moreover, because photovoltaic cable and equipment for collecting solar energy one
It rises and is set to open air throughout the year, in order to guarantee that requirement of its durability to temperature and intensity is higher and higher, existing cable passes through insulation
Rubber is often not achieved and its effect to carry out the effect of interference shielding.
Therefore, in view of the above-mentioned problems, the present invention proposes a kind of new technical solution.
Summary of the invention
The object of the present invention is to provide a kind of three cores, the cable of double insulation.
The present invention is achieved through the following technical solutions:
A kind of cable, fixed frame, inner insulating layer, external insulation layer, enhancement layer, waterproof layer and oversheath, the fixed frame are
Triangular form structure is equipped with cable core between three sides of the fixed frame, and the cable core is wrapped with inner insulating layer, the fixed frame
It is externally provided with shielding filled layer, the shielding filled layer is externally provided with external insulation layer, and the external insulation layer is externally provided with waterproof layer, described anti-
Water layer is wrapped with enhancement layer, and the enhancement layer is externally provided with oversheath.
Further, the shielding filled layer is silver-plated hollow glass micropearl.
Further, the inner insulating layer is polyvinyl chloride.
Further, the external insulation layer is Ceramic silicon rubber.
Further, the oversheath is non-metal elastic rubber material.
The beneficial effects of the present invention are: the present invention uses three-core structure, while it being equipped with double insulating layer, with prior art phase
Than, there are excellent fax Movement Capabilities, while improving the security performance of cable, meanwhile, the cable flexility is good, stability
By force, moreover, having good environmental-protecting performance and heat-resisting quantity, there is good protective effect for equipment and personal safety,
Substantially prolong the safe operating life of photovoltaic cable.
Detailed description of the invention
Fig. 1 is the structural diagram of the present invention.
Appended drawing reference are as follows:
1, fixed frame；
2, cable core；
3, inner insulating layer；
4, filled layer is shielded；
5, external insulation layer；
6, waterproof layer；
7, enhancement layer；
8, oversheath.

The present invention will be further described for example.It should be appreciated that described herein, specific examples are only used to explain the present invention, and does not have to
It is of the invention in limiting.Based on the embodiments of the present invention, those of ordinary skill in the art are not making creative work premise
Under every other embodiment obtained, shall fall within the protection scope of the present invention.
A kind of cable as shown in Figure 1, fixed frame 1, inner insulating layer 3, external insulation layer 5, enhancement layer 7, waterproof layer 6 and oversheath
8, fixed frame 1 is triangular form structure, and fixed frame is equipped with cable core 2 between 1 three sides, and cable core 2 is wrapped with inner insulating layer 3, Gu
Determine frame 1 and be externally provided with shielding filled layer 4, shielding filled layer 4 is externally provided with external insulation layer 5, and external insulation layer 5 is externally provided with waterproof layer 6, waterproof
Layer 6 is wrapped with enhancement layer 7, and enhancement layer 7 is externally provided with oversheath 8.Shielding filled layer 4 is silver-plated hollow glass micropearl, interior insulation
Layer 3 is polyvinyl chloride, and external insulation layer 5 is Ceramic silicon rubber, and oversheath 8 is non-metal elastic rubber material.
The present invention uses three-core structure, while being equipped with double insulating layer, compared with prior art, has excellent fax delivery of energy
Power, while the security performance of cable is improved, meanwhile, the cable flexility is good, and stability is strong, moreover, having good ring
Guaranteed cost and heat-resisting quantity have good protective effect for equipment and personal safety, substantially prolong photovoltaic cable
Safe operating life.
Embodiments of the present invention above described embodiment only expresses, the description thereof is more specific and detailed, but can not
