Product Description
NLL series aluminium alloy strain clamp(bolt type) is suitable for aerial line up to 35KV ,fixing aluminium wire or steel-cored aluminium wire on the strain pole, aerial insulation aluminium conductor and insulation aluminium cover are being used together for insulation protection.
AluminumAlloyStrainClamp(Straight Line Type)
Our products follow the IEC standards and can be customized various types of products according to customer requirements.
The strain clamp is primarily used to fix the conductor, ground wire terminals on tension towers of overhead lines, distribution lines and distribution equipments in substations, power plants. It also can fix the guy wire terminals on poles. Moreover, it bears all the tension of conductors, ground wires and lightning conductors.
According to its configuration an installation means, the strain clamp can be divided into compression type and explosive compression type.
Generally, malleable cast iron, steel,and aluminum alloy are used as it's materials.
All the ferrous metal should be hot-dip galvanized.
