Aluminium Bolted Strain Clamp Overhead Line Fittings Tension Clmaps.
Application :
1) NLL series aluminium alloy strain clamp(Bolts type ) is suitable for aerial line up to 35kv ,fixing aluminium wire or steel core minium wire on the strain pole,aerial insulation aluminium conductor and insulation aluminium cover are being used together.and the action is insulation protection.
2) The product body and press plate are made of high stength aluminium through heat treatment,the outside shield was made from good climate resistance insulating material.
3) This product has advantage such as high strength,good holding power ,light in weight and no magnetic hysteresis,it was belonging to power saving anchor clamp.
Structure Feature :
1) The body is made of high strength
2) Smooth surface long servile life
3) Easy installation
4) No waste electric energy
Insulation Cover Perfoemance Feature :
1) Withstand Voltage : ≥18kv keep voltage one minute not breakdown
2) Insulation resistance :> 1.0*1014 Ω
3)Environments temperature : -30 90 C
4) Weather proof performance : have good performanced after 1008 hoursartifical climate aging test.

NOTES:
(2) For optional stainless steel U bolts add “E” to catalog number. Example: NLL-1GS.
(3) It usually use with fitting like clevis and socket eye , need order separated, you can add Suffix “Q” for Clevis Fitting (Type Q-U)and add Suffix “W” for Socket Eye Fitting (W/WS Type)
