<p>Provided is a photovoltaic power collection cable which satisfies the physical characteristics (elongation, tensile strength, and retentions of elongation and tensile strength after aging), thermal deformation resistance and flame retardance as stipulated in PSE standards for the sheath. Even when scratched, the photovoltaic power collection cable does not suffer from whitening and thus has excellent surface appearance. A photovoltaic power collection cable (1) configured in such a manner that a conductor (10) is covered with an insulation layer of double wall structure which comprises both an outer insulation layer (30) and an inner insulation layer (20) made of polyethylene, wherein the outer insulation layer (30) comprises synthetic magnesium hydroxide (A) and a base resin (B) at an (A)/(B) mass ratio of 1 to 1.6, and the base resin comprises a polyolefin resin (C) and a styrenic thermoplastic elastomer (D) at a (C)/(D) mass ratio of 70/30 to 90/10, said polyolefin resin (C) comprising a polypropylene resin (E) and an ethylene/ethyl acrylate copolymer (F) at an (E)/(F) mass ratio of 2/6 to 3/5.</p> |
