Solar photovoltaic cable

Abstract

The invention discloses a solar photovoltaic cable which comprises a plurality of sets of cable conductors. Each set of cable conductors is obtained through intertwisting a plurality of tinned flexible copper cores. An insulating layer wraps the external surface of the cable conductor. An antistatic layer wraps the external surface of the insulating layer. An anti-ozone layer wraps the external surface of the antistatic layer. An elastic block is filled in a clearance between two adjacent sets of cable conductors. An armoring layer is arranged outside the elastic block. An inner sheath layer is arranged outside the armoring layer. The external surface of the inner sheath layer is provided with a corrugated aluminum wrapping layer. A calcium hydrate layer wraps the external surface of the corrugated aluminum wrapping layer. An outer sheath layer wraps external surface of the calcium hydrate layer. The cable conductor has a current transmission function. The insulating layer is made of crosslinked low-smoke halogen-free flame-retardant polyolefin so that the tinned flexible copper cores in the cable conductor has high flame resistance. The elastic blocks can improve torsion resistance of the cable conductors. Through arranging the inner sheath layer and the outer sheath layer, the cable is protected from mechanical damage.
