Product features and Installation matters

The clip body is made of high-strength aluminum alloy
Smooth appearance and long service life
Easy to install and use
No power loss, it is an energy-saving certified product.
Insulation cover performance characteristics:
▪ 1-10KV power frequency withstand voltage: ≥ 18KV, no breakdown for 1 minute;
20KV power frequency withstand voltage: ≥ 30KV, no breakdown after 1 minute of pressure maintenance;
▪ Insulation resistance: > 1.0*1014Ω;
▪ Ambient temperature: -30ºC ~ +90ºC;
▪ Weather resistance: Good performance after 1008 hours of artificial weathering test
Note:
2. The body and the pressing block are made of aluminum alloy, which has energy-saving effect,  the closing pin is made of stainless steel, and the rest are hot-dip galvanized steel parts;
3. The grip strength of the wire clamp is not less than 95% of the calculated breaking force of the wire;
4. A wear-resistant bushing is added to the iron pin hole to become a wear-resistant tension clamp.
