Product Description
The clamp body and jumper clamp are aluminium, the other parts are hot-dip galvanized steel.
NLL Strain Clamp Overhead Power Line Cable Accessory Cable Strain Tension Clamp
The products are widely used in transmission and distribution lines of electrical energy, optical cable lines and high-speed railway lines. Bolt type aluminum alloy tension clamp is used for non load-bearing connection fittings of distribution system, connection of aluminum strand or steel core or aluminum strand, connection between aluminum strand and copper strand, and connection between copper strand in non seriously polluted areas.It is designed for aerial lines up to 30kV.
1) Be suitable for fixing insulated aluminum conductor or naked aluminum conductor on the rotate angle or insulator of terminal strain pole, to fix and tighten the aerial conductor.
2) Material: body, keeper - aluminum alloy, split pin - stainless steel, others - hot-dip galvanized steel.
3) Grip strength of the clamp is more than 95% break strength of the conductor.
4) Insulation cover and strain clamp used together for insulation protection
Structural features:
1. The clamp body is made of high-strength aluminum alloy;
2. Smooth appearance and long service life;
3. Easy to install and use with spanners
4. It has no power loss and is an energy-saving certified product.
OUR PRODUCING PROCESS:
