Abstract

The utility model relates to a photovoltaic cable. The cable is composed of a halogen-free electron beam radiation polyolefin insulating layer, a halogen-free inner insulating layer, a tin-coated copper wire, a ceramic heat-conducting material, heat-resistant filler and a heat-transfer pipe. The halogen-free electron beam radiation polyolefin insulating layer is composed of an inner layer and an outer layer. The cross section of the tin-coated copper wire is circular. The tin-coated copper wire is wrapped by the halogen-free inner insulating layer. A quarter of the halogen-free inner insulating layer is wrapped by the ceramic heat-conducting material, and the residual three quarters of the halogen-free inner insulating layer are wrapped by the halogen-free electron beam radiation polyolefin insulating inner layer. The cross section of the heat-transfer pipe is circular. A half heat-transfer pipe is wrapped by the ceramic heat-conducting material. The interval among the halogen-free electron beam radiation polyolefin insulating inner layer, the heat-transfer pipe and the ceramic heat-conducting material is filled with the heat-resistant filler. The photovoltaic cable has the advantage that the heat-transfer pipe is capable of collecting heat and guiding the heat out from the cable, so that the heat dissipation of the photovoltaic cable is completed.

Description

A kind of photovoltaic cable

Technical field

The utility model relates to photovoltaic cable technical field, relates to or rather a kind of photovoltaic cable.

Background technology

Conventionally, photovoltaic cable is worked in higher temperature environment, as ambient temperature is greater than 50 degree, and general photovoltaic cable has very large electric current in when work, the two all can make photovoltaic cable self temperature in the time of work raise, if will make cable be operated in steadily in the long term in this kind of environment, just must install certain heat abstractor additional to cable, otherwise cable will produce infringement to a certain degree in use, thereby reduce useful life, increase use cost.At present, also do not there is on the market the photovoltaic cable that oneself reclaims heat and heat effectively derived to ability.

As can be seen here, still there is defect in above-mentioned existing photovoltaic cable, and is urgently improved.

Because the defect that above-mentioned existing photovoltaic cable exists, the design people is based on being engaged in this type of product design manufacture for many years, amass and have abundant practical experience and professional knowledge, actively research and innovation in addition, to founding a kind of photovoltaic cable, can improve the general molding structure of existing photovoltaic cable on the market, make it have more competitiveness.Through constantly research, design, and after repeatedly studying sample and improving, finally create the utility model having practical value.

Summary of the invention

Technical problem underlying to be solved in the utility model is, overcome the defect that existing photovoltaic cable exists, and a kind of photovoltaic cable is provided, overcome existing photovoltaic cable and had the defect that cannot reclaim heat, improve the heat-sinking capability of photovoltaic cable, and then the useful life of having improved photovoltaic cable.

The utility model solves its technical problem underlying and realizes by the following technical solutions.According to the photovoltaic cable the utility model proposes, by Halogen electron beam irradiation polyolefin insulation layer, Halogen inner insulating layer, tinned copper wire, ceramic material, thermal resistance is filled and heat-transfer pipe composition, Halogen electron beam irradiation polyolefin insulation layer comprises Halogen electron beam irradiation polyolefin insulation internal layer and the outer two parts of Halogen electron beam irradiation polyolefin insulation, Halogen electron beam irradiation polyolefin insulation internal layer outer wrapping Halogen electron beam irradiation polyolefin insulation skin, tinned copper wire cross section is rounded, tinned copper wire coated outside Halogen inner insulating layer, Halogen inner insulating layer has 1/4th part to be wrapped up by ceramic material outward, the part of residue 3/4ths is wrapped up by Halogen electron beam irradiation polyolefin insulation internal layer, the cross section of heat-transfer pipe is rounded, heat-transfer pipe outside has 1/2nd to be wrapped up by ceramic material, two fan-shaped ceramic materials of parcel Halogen inner insulating layer and heat-transfer pipe are connected by the strip bar of being made up of ceramic material, position, space between Halogen electron beam irradiation polyolefin insulation internal layer and heat-transfer pipe and ceramic material is that thermal resistance is filled.

Cable described in the utility model precision metallic material, the beneficial effect of its generation is: the heat-transfer pipe that photovoltaic cable comprises can be collected heat, and heat is derived from cable, completes the process that photovoltaic cable is dispelled the heat.
