Solar Cables 1.5kV DC

Introduction

CableGrid’s PV Solar cables are designed for connecting photovoltaic power supply systems. Cables are dedicated to the photovoltaic system direct current (D.C.) side with a nominal D.C. voltage of a 1.5kV. These cables can be used indoor & outdoor for flexible and fixed installations with high mechanical strength in extreme weather conditions. cables are designed to withstand the demanding environmental conditions that arise in any fixed, mobile, roof or architecturally integrated photovoltaic installation.

Why CableGrid Solar Cables

CableGrids Solar cables provides the maximum efficiency and guarantee energy transmission throughout the useful life of your installation

Application

CableGrids PV Solar cables are designed for connecting photovoltaic power supply systems.

These cables are suitable for permanent outdoor long-term use, under variable and harsh climate conditions. They are designed and tested to operate at a normal maximum conductor temperature of 90°C and for 20,000 hours up to 120°C. Therefore, the expected period use is 30 years under normal usage conditions

Design

Solar 1.5kV DC cables are designed and manufactured to EN 50618, IEC 62930, AS/NZS 5000.1 and other relevant standards.
Conductor – Flexible Electrolytic Tinned Class 5 Copper to EN 60228 or IEC 60228
Insulation – Crosslinked Halogen Free & Flame Retardant Insulation, Colour: Red or Black
Outer Sheath – Crosslinked Halogen Free & Flame Retardant UV and ozone resistant Sheath in Black or Black with Red Strips
Termite Protection: Nylon jacket termite protection can be offered for cables susceptible to attack from rodents and termites.
5kV DC feeder cables can also be offered with X-90 Insulation and HDPE or PVC over sheath upon request.
