JBTL series special-shaped parallel groove clip is suitable for non-load connection and branch of wires in overhead electric lines, and it is used as protective insulation with insulation cover.

BASIS DATA

Chapter 1 –Introduction Of   PG  Clamp     

Parallel groove clam  are mainly used for transmitting current between the interconnected conductors. Besides this main area of application parallel groove clamps are also used for safety loops and therefore they must provide an adequate mechanical holding strength.

If conductors made of different materials are to be connected this can be done by using bimetallic aluminium copper PG clamp. In bimetallic PG clamps, the two bodies are made out of high strength aluminium alloy, and to tight a copper conductor, one groove is made with aluminum alloy and welded by hot forged bimetallic sheet . The bolts are made out of hard steel (8.8) and Dacronatized.

 Chapter 2–Performance Characteristics Of   PG  Clamp

• Power frequency voltage: ≥18kV voltage holding for 1 minute without breakdown
• Insulation resistance: > 1.0×1014W
• Ambient temperature: -30℃ ~ 90℃
• Weather resistance: good performance after 1008 hours of artificial weather aging test

 Chapter 3 –Insulation cover performance feature

• Withstand voltage: ≥18kV keep voltage one minute not breakdown
• Insulation resistance: ＞ 1.0×1014Ω
• Environment temperature: -30℃~90℃
• Weather proof performance:have good performance after 1008 hours artificial climate aging test
