1500V DC Twin Core Solar Cable , 6mm 2 Core Cable Low Smoke Emission

1500V DC Twin Core Solar Cable — 6 mm² 2 Core Low Smoke Emission

This 1500V DC twin core solar cable in 6 mm² features a low smoke emission outer sheath — making it suitable for solar installations in enclosed, semi-enclosed, and populated areas where smoke generation from cable fires must be minimised to protect evacuation routes and building occupants. The low smoke sheath compound produces dramatically less smoke density than standard XLPO or PVC when exposed to flame, complying with IEC 61034-2 smoke density testing requirements.

The twin 6 mm² tinned copper conductors are individually insulated with XLPO and enclosed in the low-smoke outer sheath — combining the electrical performance of standard H1Z2Z2-K solar cable with the enhanced fire safety of low-smoke zero-halogen (LSZH) sheath materials. Rated 1500V DC; temperature range ‑40°C to +90°C; UV and ozone resistant outer sheath.

• Zero halogen sheath — no HCl toxic gas emission on burning
• Ambient temperature ‑40°C to +90°C; UV and ozone resistant
• Conductor identification: black/red or print-marked
• Suitable for enclosed solar installations and building-integrated PV
• Compliant with EN 50618 / IEC 62930 basis

Electrical & Mechanical Specifications

Typical Applications

• Building-integrated PV (BIPV) in occupied commercial buildings
• Solar installations in underground car parks and enclosed structures
• Hospital, school, and public building rooftop solar DC wiring
• Solar installations in tunnels and enclosed transportation infrastructure
• Data centre rooftop solar where smoke-free cables are mandatory
• Any PV project where the project specification mandates LSZH DC cables

Selection Guide

When Must You Use Low Smoke Solar Cable?

Specify low smoke solar cable wherever the project specification, local building code, or fire engineering report identifies solar DC cables as cables in occupied or enclosed spaces. In the UK, BS 9999 (fire safety in buildings) and the IET Wiring Regulations (BS 7671) recommend LSZH cables in occupied buildings. In Europe, CPR (Construction Products Regulation) Cca or Dca fire class cables may be required — check with your project fire engineer or AHJ.
