1. Excellent Material Quality
The housing is typically made of high-strength anti-oxidation aluminum alloy via die casting, featuring no hysteresis or eddy current phenomena. It has good electrical conductivity and corrosion resistance.
The wedge core is generally made of weather-resistant insulated reinforced engineering plastics or high-strength reinforced nylon materials, ensuring excellent insulation performance.
2. Unique Structure
Adopts a wedge-type structure, where the grip on the conductor is directly proportional to the tension, with self-tightening characteristics.
The housing has a C-shaped open design, making it easy to insert the inner wedge and conductor for convenient installation.
The outlet part is arc-shaped, which can hold the conductor over a large area to prevent conductor creep.
3. Superior Insulation Performance
The supporting insulation cover has high power frequency withstand voltage performance. For example, it can withstand ≥18kV at 1-10kV power frequency without breakdown for 1 minute, with an insulation resistance >1.0×10¹⁴Ω.
It can adapt to environmental temperatures of -30°C to 90°C and has good weather resistance. After 1,008 hours of artificial climate aging tests, its performance remains excellent.
