Abstract
The utility model provides the fire-retardant photovoltaic cable of a kind of novel environment friendly, belongs to solar power generation photovoltaic cable technical field, is intended to solve existing solar power generation photovoltaic cable structural design unreasonable, the problem that cable jacket intensity is low.The cable body that it adopts is made up of the cable core outer cladding insulating barrier of multiply tinned copper wire stranded conductor, is coated with external sheath layer again outward at insulating barrier; Insulating barrier adopts ethylene methacrylic silicon rubber to be that the insulating material of base-material is made, and external sheath layer is made up of hot shortness's polyurethane TPU elastomer.It is simple and practical, and application life is long, easy to use, is applicable to the photovoltaic cable of solar power generation.
Description
Technical field
The utility model belongs to a kind of photovoltaic cable utilizing solar power generation in field of cable technology.
Background technology
Heliotechnics has become one of following green energy resource technology, and the application of solar energy or photovoltaic (PV) is day by day extensive, and the connection that photovoltaic cable is mainly used in photovoltaic module is the key component in photovoltaic generation.Because photovoltaic cable is exposed under sunlight often, solar energy system usually can use in harsh environments, as high temperature and ultraviolet radiation; As in Europe, during fine day, will the scene temperature of solar energy system be caused up to 100 DEG C.In known technology, mostly existing solar power generation photovoltaic cable is the cable body of the copper wire core outer cladding insulating barrier adopted, but limit by its structure, its structural design is unreasonable, especially during installation and maintenance, cable can connect up on the sharp edge of roof structure, cable must bear pressure simultaneously, bending, tension force, be stretched across load and brute force attack, because cable jacket insufficient strength, cause the frangible cracking of cable cover(ing), even cable insulation can be decomposed, thus affect the useful life of whole cable, even cause short circuit, fire and personnel injure the problems such as dangerous, also the useful life of whole solar power system will be had influence on, make troubles to actual use.
Utility model content
In order to overcome the deficiencies in the prior art, solve existing solar power generation photovoltaic cable structural design unreasonable, the problem that cable jacket intensity is low.The purpose of this utility model is to provide a kind of simple and practical, compression resistance, bending, tension force, is stretched across load and anti-brute force attack power is strong, and application life is long, new-type photovoltaic cable easy to use.
The technical scheme in the invention for solving the above technical problem is:
The fire-retardant photovoltaic cable of a kind of novel environment friendly, the cable body that it adopts is that the conductor outer cladding insulating barrier of cable core formed, and is coated with external sheath layer again outward at insulating barrier.
The fire-retardant photovoltaic cable of above-mentioned novel environment friendly, described cable core is multiply tinned copper wire stranded conductor, and insulating barrier adopts ethylene methacrylic silicon rubber to be that the insulating material of base-material is made, and external sheath layer is made up of hot shortness's polyurethane TPU elastomer.
When the utility model uses, according to designing requirement, load is in the photovoltaic module of solar power generation.Product operating characteristic: 1. rated voltage Uo/U is 0.6/1kV; 2. the long-term permission working temperature of cable conductor is 120 DEG C; 3. the minimum bending radius of cable is 6 times of cable size; Environmental protection LSOH anti-flaming.
Because the utility model design have employed technique scheme, it have employed the beam crossover link cable that cross-linked polymer material manufactures, and efficiently solves existing solar power generation photovoltaic cable structural design unreasonable, the problem that cable jacket intensity is low.Also show through solar power plant's (station) actual tests result on trial, it compared with prior art, have simple and practical, compression resistance, bending, tension force, be stretched across load and anti-brute force attack power is strong, high temperature resistant, ultraviolet radiation, ozone, dramatic temperature change and chemical erosion, application life is long, and the cable of this kind of low smoke and zero halogen material can not produce toxic gas when breaking out of fire, can not work the mischief to staff and environment, the advantage such as easy to use, is applicable to the photovoltaic cable of solar power generation.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is described in further detail.
Accompanying drawing 1 is the structure diagram of the utility model embodiment.
In accompanying drawing, each label is: 1 cable core; 2 insulating barriers; 3 external sheath layers.
Embodiment
Embodiment as shown in Figure 1, the cable body that the utility model adopts is made up of the cable core 1 outer cladding insulating barrier 2 of multiply tinned copper wire stranded conductor, outside insulating barrier 2, be coated with again external sheath layer 3.Wherein: insulating barrier 2 for ethylene methacrylic silicon rubber be the insulating material of base-material, the tensile strength >=6.5MPa of insulating material; External sheath layer 3 is the tensile strength >=8.5MPa of the Thermoplastic elastomer of polyurethane TPU, jacket material.
Claims (2)
1. the fire-retardant photovoltaic cable of novel environment friendly, it is provided with cable body, it is characterized in that, cable body is that the conductor outer cladding insulating barrier (2) of cable core (1) formed, and is coated with again external sheath layer (3) outward at insulating barrier (2).
2. the fire-retardant photovoltaic cable of novel environment friendly according to claim 1, is characterized in that, cable core (1) is multiply tinned copper wire stranded conductor.
