Description

LSOH anti-flaming photovoltaic generation private cable

Technical field

This utility model relates to electric wire field, specially LSOH anti-flaming photovoltaic generation private cable.

Background technology

Enhancing along with mankind's environmental consciousness, solar energy generation technology application is the most extensive, solar energy acquisition system should select the area of abundance at sunshine, and population is relatively fewer, will not be because of artificial Influence on Architecture daylighting, the photovoltaic plant having obtained power construction in China focuses mostly in the Inner Mongol, Xinjiang, Ningxia, the regions such as Gansu, these region common features are located at inland areas, height above sea level is higher, the few water smoke of rarefaction of air, dry, short of rain how fine, sunshine-duration is long, relatively empty big, it is far from the crowd, building is few, there are enough daylighting areas, in this case, sunlight is few through atmospheric loss, radiation is many, certain areas during fine day, the scene temperature of solar energy system is up to 100 DEG C, therefore photovoltaic cable must resist extreme climate environment, so the high temperature resistant of photovoltaic cable and anti-ultraviolet property are proposed higher requirement.

At present, photovoltaic cable effectiveness is low, poor anti jamming capability, easy firing, and produces a large amount of toxic gas, outer is easily destroyed, and easily causes broken string during laying and using or draw and attenuate, and service life is short.

Utility model content

In order to solve above technical problem, this utility model one is rational in infrastructure, and effectiveness is high, there is preferable tensile strength, anti-flaming thermal-insulation performance, high temperature resistant, the LSOH anti-flaming photovoltaic generation private cable of UV resistant, the following is concrete technical characteristic:

LSOH anti-flaming photovoltaic generation private cable,

Including four conductor wire cores being centrosymmetric, it is provided with optical fiber between each conductor wire core, wherein around conductor wire core and optical fiber, it is filled with ceramic fiber layer, metal armor layers is had in ceramic fiber layer outer wrap, high-temperature-resistant layer is had in metal armor layers outer wrap, at high-temperature-resistant layer outer wrap waterproof layer, waterproof layer outer wrap has sheath.

As preferred technical scheme, described conductor wire core includes center conductor, is provided around inner conducting layer at center conductor, and inner conducting layer is coated with insulating barrier, is coated with outer conducting layer at insulating barrier, is coated with insulation protective jacket at outer conducting layer.

It is that PVC conductive material is made as preferred technical scheme, described inner conducting layer and outer conducting layer.

As preferred technical scheme, described optical fiber is coated with internal shield, is coated with insulation protective jacket at internal shield.

As preferred technical scheme, described cable center is additionally provided with a square reinforcement, and described conductor wire core is arranged around this reinforcement.

As preferred technical scheme, described metal armor layers is entwined by 150～180 tinsels.

As preferred technical scheme, described sheath is made up of low smoke, zero halogen environment-friendly polyolefin material.

Owing to have employed technique scheme, LSOH anti-flaming photovoltaic generation private cable, optical fiber can transmit optical signal and the signal of telecommunication, it is greatly enhanced the resistance to elevated temperatures of cable, tensile strength by arranging ceramic fiber layer and high-temperature-resistant layer, simultaneously, improve the bending property of cable, creep-resistant property and decay resistance etc., it is possible to ensure cable long term overloading and overheated time keep continuous stable performance etc., improve load-bearing and the resistance to tension of cable.
