The details of strain clamp: 

The strain clamps is used for fixing conduct wires and linghting rods on nonlinear pole of aerial electric lines or in transforming stations. They are connected to the stain insulators by connecting clamp. Or fix lightning rods on the pole tower.

According to the structures and installation methods, they are divided into three types including bolt type, compressed type and wedge type.

Type	Diameter of  stranded wire	U bolt		U.T.S(KN)	Cover used
		Nos	Dia
NLL-1	5.0-10.0	2	M10	40	JNL-1
NLL-2	10.1-14.0	2	M12	40	JNL-2
NLL-3	14.1-18.0	3	M12	70	JNL-3
NLL-4	18.1-23.0	3	M12	90	JNL-4

According to different materials, they can be divided into two types: Forging cast iron and aluminum alloy of which, the aluminum alloy clamp is also the energy saving anchor clamp. 

Used for: 

NLL series is suitable for aerial line up to 35KV, fixing alumium wire or steel core aluminum wire on the strain pole.

Features of NLL series bolt type strain clamp:NLL series bolt type strain clamp has advantage of saving energy, with heat treatment, high intensity.

Specified Failing load of NLL series bolt type strain clamp is from 40KN to 120KN.
