Description

Solar photovoltaic cable with tension releasable structure

Technical field

A kind of the utility model category photovoltaic cable technical field, and in particular to solar energy with tension releasable structure Luff cable.

Background technology

All it is single structure in photovoltaic cable standard at present, and common two-core cable is circular or flat type, round cable Technique is relative complex and material consumption is high, and flat type cable is the direct extrude sheath outside two core insulations, during this structure construction It is not easily stripped, conductor easily draws and attenuates when laying over long distances, or even breaks.In addition, photovoltaic cable structure seems simple, but its work For environment, the moment under illumination, can usually use, such as high temperature and ultraviolet radiation in harsh environments. Some countries of Europe, are up to 100 DEG C during fine day, by the scene temperature for causing solar energy system plus combustible in working environment very It is more, once these combustibles are unable to bear scorching for high temperature, dieseling just occurs, causes burning, whole photovoltaic will be caused The appearance for the problems such as system is damaged or causes electric short circuit, fire and casualties danger.It is therefore desirable to propose to improve.

Utility model content

The technical problem that the utility model solves：A kind of solar photovoltaic cable with tension releasable structure is provided, The utility model uses the 5th kind of tin plating soft copper conductor by design, design, can prevent conductor indium and improve the corrosion-resistant of conductor Property；And aramid yarn reinforcement is added among in conductor strand, improves the tensile strength of cable, wrapped isolation outside conductor Layer can prevent from, because insulation squash type production causes in insulating cement insertion copper wire gap, being easy to wire stripping；It is arranged in parallel at two The outer extrude sheath material of insulated wire cores, and the dowel that cross section is dumbbell shaped is formed, it is easy to core during construction to separate, cable has The excellent properties such as low smoke and zero halogen, fire-retardant, tension, easily separated, resistance to ozone, UV resistant, meet photovoltaic system service requirement.

The technical solution adopted in the utility model：Including two insulated wire cores, the every insulated wire cores include reinforcer, Conductor, separation layer and insulating barrier, the conductor make to be equipped with reinforcer among it when twisted, and isolation is surrounded with outside the conductor Layer, the separation layer are extruded with insulating barrier outside, once extrude to form shield outside it after two insulated wire cores are arranged in parallel Dowel is formed among jacket layer and restrictive coating.

Wherein, the reinforcer uses aramid fiber yarn material.

The conductor uses the 5th kind of tin plating soft copper conductor.

The separation layer is made of cotton paper band.

The insulating barrier is using the special high insulating property irradiation crosslinked polyolefin insulating material system of 125 DEG C of photovoltaic cables Into.

The restrictive coating and dowel are using the special cross-linking radiation polyolefin jacket material system of 125 DEG C of photovoltaic cables Into.

The utility model compared with prior art the advantages of：

1st, conductor uses the 5th kind of tin plating soft copper conductor in this programme, and in conductor strand among add aramid yarn Reinforcer, it so can effectively prevent conductor indium and improve the corrosion resistance of conductor, improve the tensile strength of cable；

2nd, can be prevented in conductor peripheral hardware separation layer because insulation squash type production causes insulating cement insertion copper wire gap in scheme In, it is easy to cable wire stripping；

3rd, this programme extrude sheath material outside two insulated wire cores arranged in parallel, and form the company that cross section is dumbbell shaped Muscle is connect, is easy to core during construction to separate；

4th, insulating barrier and restrictive coating use the special cross-linking radiation polyolefin of 125 DEG C of photovoltaic cables in this programme, make cable With low-smoke non-halogen flame-retardant performance, meet photovoltaic system service requirement.

Brief description of the drawings

Fig. 1 is structural representation of the present utility model.

Embodiment

1 embodiment of the present utility model is described below in conjunction with the accompanying drawings.

Solar photovoltaic cable with tension releasable structure, as shown in figure 1, including two insulated wire cores, it is described every Root insulated wire cores include reinforcer 1, conductor 2, separation layer 3 and insulating barrier 4, wherein, the conductor 2 uses the 5th kind of tin plating soft copper Conductor, conductor indium can be prevented, improve the corrosion resistance of conductor；The conductor 2 makes to be equipped with reinforcement among it when twisted Part 1, it is preferred that the reinforcer 1 uses aramid fiber yarn material, improves the tensile strength of cable；Isolation is surrounded with outside the conductor 2 Layer 3, the separation layer 3 are made of cotton paper band, and separation layer 3 can be prevented because insulation squash type production causes insulating cement embedded conductor In 2 copper wire gap, it is easy to cable wire stripping；Insulating barrier 4 is extruded with outside the separation layer 3, the insulating barrier 4 uses 125 DEG C of light The special high insulating property irradiation crosslinked polyolefin insulating material of luff cable is made.

Once extrude to form restrictive coating 6 and 6 middle shape of restrictive coating outside it after two insulated wire cores are arranged in parallel Into dowel 5, it is dumbbell structure two insulated wire cores arranged in parallel is formed cross section, is easy to core during construction to separate； The restrictive coating 6 and dowel 5 are made of using the special cross-linking radiation polyolefin jacket material of 125 DEG C of photovoltaic cables.Cable With low-smoke non-halogen flame-retardant performance, meet photovoltaic system service requirement.

Above-described embodiment, simply preferred embodiment of the present utility model, not it is used for limiting the utility model practical range, Therefore all equivalence changes done with content described in the utility model claims, the utility model claims model all should be included in Within enclosing.
