Item Name: Aluminum Alloy Strain Clamp/Nll-2 Strain Clamp2. Specifications:Nll-1, Nll-2 Aluminum Die-Casting Bolt Strain Clamps for Overhead Line fitting3. Usage:Bolt type pole transmission line hardware strain clamp is used in high voltage pole line to connect power fitting string or insulators4. Material: Aluminum alloy5. Characteristic: High tensile strength, long elongation, hot dip galvanized,6. Material:The clamp body and keepers are aluminum alloy, the cotter-pin is stainless steel, the other parts are hot-dip galvanized steel.NLL Seriesaluminum alloy strain clampThe 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.TypeDiameterofstrandedwireUboltU.T.S(KN)CoverusedNosDiaNLL-15.0-10.02M1040JNL-1NLL-210.1-14.02M1240JNL-2NLL-314.1-18.03M1270JNL-3NLL-418.1-23.03M1290JNL-4According 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.
