The forged aluminium clamps wasuse for aluminium to aluminium connection throughout the conductor range.
The clamps have serrated transverse grooves for maximum conductor contact, use dacromet steel bolts and tilise belleville washers to prevent thermal ratcheting under cyclic loads.
The clamps are coated with an oxide inhibitor. And hot-dip galvinized steel bolts and nuts was on requirment, also we can change to stainless bolts and nuts with washers.
Material:
- Body: High strength corrosion resistant aluminium
- Bolts: DIN 933, steel, 8.8, Dacromatized
- Nuts: DIN 934, steel, Dacromatized. pressed into lower clamp body
- Spring: DIN 127, steel, Dacromatized washers: Dacromatized.
