Interconnecting Clamp Accessory for Solar PV Racking Systems

Q1: What is an interconnecting clamp?

A: The interconnecting clamp is a connecting fitting for solar PV racking systems. It mechanically joins two solar mounting rails end‑to‑end, extending the total rail length, ensuring structural continuity for long‑span PV arrays.

Q2: What material is used?

A: Main body: 6005‑T5 / 6063‑T5 anodized aluminum alloy. Matching bolts and nuts: SUS304 stainless steel. Good anti‑corrosion performance for coastal and harsh outdoor environments.

Q3: What is its core function?

A: Connect two mounting rails end‑to‑end to realize length extension. Ensures stable mechanical connection, transfers wind and snow loads evenly across rail joints, maintains overall racking structural strength.

Q4: Which rails can it match?

A: Designed for our standard solar mounting rails. For third‑party profiles, please provide rail cross‑section drawings for compatibility verification.

Q5: Where is it applied?

A: Widely used in rooftop PV, ground‑mount solar farm, solar carport and BIPV projects. Required when single rail length cannot meet layout demands.

Q6: How to install the interconnecting clamp?

A: Slide the clamp into the inner T‑slot of two aligned rail ends, fasten the bolts with proper torque. No on‑site welding or cutting is required. Follow installation manual for recommended torque value.

Q7: Will there be deformation or gap at rail joint?

A: Precise extrusion manufacturing ensures good fitting. Proper bolt‑torque installation minimizes gaps. It also reserves minor thermal‑expansion allowance for temperature variation.

Q8: Does it affect system load‑bearing capacity?

A: When installed per engineering instructions, the joint meets system wind‑load and snow‑load requirements. Do not over‑extend rails beyond project design parameters.
