Product Detail
Product Highlights: End Clamp Kit – TSUN Solar End Clamp Kit | Technical White Paper
1. Revolutionary Structural Design
3D Locking Mechanism
Patented interlocking teeth design provides 1200N clamping force, supporting wind resistance up to level 17 (wind speed 60 m/s).
Self-Adjustment
Compatible with frame thicknesses of 30–50 mm (covers 166 / 182 / 210 mm modules).
±10 mm lateral tolerance eliminates the influence of on-site installation errors.
2. Military-Grade Material Standards
6061-T6 Aerospace Aluminum
Tensile strength ≥ 290 MPa; corrosion resistance is 5× higher than galvanized steel.
304 Stainless Steel Fasteners
Nickel content ≥ 8.5%; passes 2000-hour salt spray test with zero rust.
UV5000h Protection
Anodized aluminum surface extends UV aging resistance lifespan by 3×.
3. Versatile Application Scenarios
① Residential Roof Systems
Pre-set torque markers allow for single-person installation in 30 seconds per module.
Passes 5400 Pa wind uplift test (equivalent to a level 18 typhoon).
② Commercial and Industrial PV Systems
Compatible with 8 roof types including metal, concrete, and asphalt.
Non-penetrative clamp design protects building structural integrity.
③ High Altitude / Coastal Projects
Tested from -50°C to +85°C for extreme climate adaptability.
Certified for salt corrosion and UV resistance, ideal for coastal or high-radiation regions.

FAQ Highlights
P1: How does the clamp fit a variety of frame thicknesses?
A: Self-adjusting nut design fits 30–50 mm frames via a rotating adjustment ring—no part replacement required.
P2: How safe is it under extreme wind conditions?
A: Tested to 5400 Pa wind pressure (level 18 typhoon equivalent); 3D locking design triples wind resistance. Dual anti-loosening mechanisms on key joints ensure lasting stability.
P3: Is the clamp suitable for coastal, high-corrosion environments?
A: Yes. 304 stainless steel and anodized aluminum construction withstands 2000-hour salt spray testing, with a corrosion rate <0.01 mm/year and service life exceeding 25 years.
P4: Are special tools needed for installation?
A: No. 95% of installation tasks can be completed with a standard 13 mm wrench. Pre-set torque indicators ensure precision. New installers can be trained in under 1 hour.
P5: How is long-term clamping force ensured?
A: Spring washer and anti-loosening nut provide dual locking. Clamp force loss remains below 2% over 25 years. Key components are covered by a 12-year structural warranty.
