The following testing shall be carried out

Dead End Clamp ,Anchoring Clamp

The clamps should be designed to Anchor LV AB cable with insulated messenger. The clamp
should anchor/hold the neutral messenger without damaging the insulation.
The clamp should conform to the standard NFC 33041 and 33042 or equivalent. The clamp
body should be made of corrosion resistant Aluminium alloy, bail should be of stainless steel
and self adjusting wedges should be weather and UV resistant polymer.
Anchoring assemblies are used to firmly attach the messenger of ABC to a support and
transmit the mechanical tension at the end of a run or to the supporting structures at a major
change in direction.

neutral messenger should be fixed by an adjustable grip device.
The suspension clamp shall be manufactured from weather and UV light resistant reinforced
nylon and aluminum alloy. The clamp should provide an additional insulation between the
cable and the pole.
Clamps should be fixed with pole by eyehook/bracket. Breaking load should not be less than
15kN
Suspension Assembly is used for supporting an ABC by installation on the messenger at an
intermediate point of support such as a pole. It can accommodate small angles of deviation up
to 30^o. The clamp should hold insulated messenger of diameter range from 6mm up to 12 mm.
