Solar mounting systems YG cable, also known as yellow‑green earthing cable, is a dedicated protective earth conductor designed for roof‑mounted PV busbar earthing applications. Constructed with high‑purity stranded copper conductor and durable yellow‑green PVC insulation, it delivers low contact resistance and reliable fault‑current dissipation for rooftop solar systems.

Featuring good UV‑resistance, anti‑aging and moisture‑proof performance, this cable adapts well to open‑air rooftop environments with wide temperature fluctuation. It establishes equipotential bonding among solar racks, mounting frames and roof earthing busbars, diverting leakage current and lightning surge safely to earth, preventing electric shock and equipment burnout risks.
YG earthing cable meets IEC 60227 safety standard.
Relevant test reports like CE and RoHS can be provided upon request.
Custom length, pre‑crimped cable lugs and special marking are available for bulk orders.
Q1: What is YG Cable used for?
A: YG cable, yellow‑green earthing cable, is specially designed for rooftop PV projects. It connects solar mounting frames, racking and roof earthing busbar for equipotential bonding. It provides low‑impedance path to discharge fault current, leakage current and lightning surge, protecting equipment and personnel from electric shock risk.
Q2: Why yellow‑green insulation colour?
A: Yellow‑green is the globally‑recognized protective earth colour defined by IEC 60446. The special colour avoids mis‑wiring during installation and maintenance for rooftop solar sites.
Q3: What conductor material do you adopt?
A: Stranded high‑purity copper conductor. Multi‑stranded structure brings good flexibility for on‑site bending and wiring on complex roof layouts. PVC insulation features UV‑resistance, anti‑aging and moisture‑proof for outdoor rooftop environment.
Q4: How to select correct cross‑section size?
A: Common sizes range from 2.5mm² to 35mm². Select according to local PV electrical codes, fault‑current value and cable run length. For most residential rooftop PV systems, 6mm²‑10mm² is widely adopted for busbar earthing bonding.
Q5: Can YG cable work with cable lugs?
A: Yes. It perfectly matches copper cable lugs. Use proper hydraulic or hand crimping tools to get tight gas‑tight crimp connection, preventing loose contact and overheating.
