Cables, Trays, Grounding & Fasteners
4 Product Series · 15 Models available
The AC side and the structural grounding of a plant are easy to under-specify, yet they carry every kilowatt to the point of connection and protect both equipment and people from fault current. QDTB supplies XLPE-insulated AC power cables, galvanised cable trays, earthing conductors and stainless fasteners as a matched set. Cables are sized to the inverter output and run length, trays route and support them through the plant, and a low-impedance grounding system bonds frames, arrays and equipment to dissipate lightning and fault current safely. Consistent materials and corrosion protection across the set mean the installation stays safe and serviceable for the plant's full life.

Frequently Asked Questions
What cable size do I need for the AC side?
The cross-section depends on the inverter output current and run length; it must keep voltage drop within code limits and match the upstream breaker rating.
Tray or conduit — which is better?
Trays suit multi-cable runs and simplify maintenance and expansion; conduit offers mechanical protection where the run is exposed or buried.
Why is grounding critical in a PV plant?
A low-impedance earth dissipates lightning and fault current, protects against electric shock and prevents damage to inverters and electronics.
What material is best for fasteners?
Stainless steel (A2/A4) resists corrosion in outdoor and coastal environments, avoiding seized or rusted fixings over the plant's life.
Can you supply the complete grounding set?
Yes, earthing conductors, clamps, rods and bonding hardware are supplied together for a consistent, compliant installation.
