The insulated wedge clamp secures and tensions overhead insulated conductors in distribution lines through reliable mechanical anchoring that preserves cable insulation integrity. Its wedge mechanism tightens under load, providing self-tightening action that maintains stable tension without requiring maintenance.
Constructed from high-strength aluminum alloy and UV-resistant, fiberglass-reinforced plastic, the clamp withstands environmental exposure while distributing load evenly across the cable to reduce stress points. Models accommodate cable diameters from 8.5 mm to 33 mm, with grip strengths ranging from 3.4 kN to 28.2 kN and failure loads up to 52.1 kN. Voltage compatibility spans 1 kV, 10 kV, and 20 kV systems.
Operating performance remains consistent across temperatures from -40°C to +60°C, with resistance to UV exposure, humidity up to 95%, and corrosive elements. The design prevents cable slippage while maintaining electrical integrity through low-resistance, high-conductivity connections. Compliance with CE and ISO9001 standards ensures reliable performance.
Applications include overhead power lines, street lighting systems, telecommunications networks, renewable energy installations, industrial facilities, and substation connections. Installation requires positioning the clamp around the insulated cable, tightening the wedge mechanism to achieve firm grip, and verifying proper tension and security using basic tools.

Frequently Asked Questions (FAQS)
How does the insulated wedge clamp work?
The insulated wedge clamp operates through a wedge mechanism that, when bolts are tightened, forces the clamp's arms to close around the cable, providing a secure grip without damaging the insulation. It is cast from high-strength aluminum alloy, offering advantages such as strength, good holding power, light weight, no magnetic hysteresis loss, and easy installation.
What types of insulated cables can the wedge clamp be used with?
The insulated wedge clamp is suitable for insulated cable sizes used in low-voltage power distribution systems, particularly overhead insulated conductors like JKLYJ series, with cable outer diameters ranging from approximately Φ19mm to Φ33mm.
What factors should I consider when selecting an insulated wedge clamp?
When selecting an insulated wedge clamp, consider the cable size and type, the operating voltage of the system (e.g., up to 20kV), and the installation environment, including temperature range, humidity, UV exposure, and corrosive conditions. Also, ensure the clamp provides adequate clamping force and meets relevant certification standards.
