Description

TECHNICAL FIELD

[0001] The utility model relates to the field of cable, especially a light weight photovoltaic cable. BACKGROUND

[0002] At present, when installing photovoltaic power generation equipment, multiple photovoltaic cables are often laid together. At present, when laying photovoltaic cables, in order to avoid the scattering of photovoltaic cables, multiple photovoltaic cables are mostly bundled together by using a cable tie. Since the bundling by using a cable tie is generally tight, and the cable tie generally needs to be cut off to replace and maintain the photovoltaic cable, the photovoltaic cable is easy to become scattered when the cable tie is cut off, which brings great inconvenience to the maintenance of the photovoltaic cable. Although a positioning clamp capable of clamping and positioning photovoltaic cables has appeared, since there is no auxiliary clamping structure on the existing photovoltaic cable, the positioning clamp is directly clamped on the insulating skin of the photovoltaic cable. Due to the influence of the hard core inside the photovoltaic cable, in order to facilitate the clamping of the positioning clamp on the photovoltaic cable, and in order to avoid scratching the wire skin of the photovoltaic cable during the clamping process of the positioning clamp, the positioning clamp of the present is mostly not tightly clamped on the photovoltaic cable, and the photovoltaic cable is easy to slide on the positioning clamp. Since photovoltaic equipment is an outdoor device, and the existing photovoltaic cable is mostly exposed, the photovoltaic cable is easy to shake due to the action of outdoor wind, which easily leads to the sliding of the photovoltaic cable on the positioning clamp or the swinging of the photovoltaic cable relative to the positioning clamp. During this process, the hard core is easy to be squeezed together with the positioning clamp to press the insulating skin, which easily leads to the occurrence of large friction and / or bending on the position where the insulating skin contacts the positioning clamp, thereby easily leading to the wear of the insulating skin of the photovoltaic cable, the acceleration of the aging speed, the reduction of the service life, the reduction of the safety, and other situations, and further easily existing a relatively large safety hazard. Therefore, it is necessary to design a light weight photovoltaic cable to solve the above technical problems. SUMMARY

[0003] The utility model aims at solving the above problems and deficiencies, and provides a light weight photovoltaic cable, which can be stably clamped and positioned without the need for a cable tie, thereby facilitating the improvement of the convenience of maintenance and repair, and can reduce the probability of large friction and large bending of the insulating skin while meeting the clamping and positioning, which can facilitate the reduction of the probability of the wear, the acceleration of the aging speed, the reduction of the service life, the reduction of the safety, and other adverse situations of the photovoltaic cable, thereby facilitating the improvement of the safety in use.
