The strain/tension clamp is used for corner, connection, and terminal connection. Spiral aluminum clad steel wire has extremely strong tensile strength, no concentrated stress, plays a role in the protection and auxiliary vibration reduction of optical cable.
The whole set of optical cable tension bearing includes: tension outer pre-twisted wire, inner pre-twisted wire, supporting connection fittings. The wire clamp grip power is not less than 95%of the rated tensile strength of the optical cable. it is easy to install and fast, which reduces the construction cost.
NLL series bolt-type aluminium alloy tension clamps are suitable for overhead lines of 20KV and below. Fixing aluminium stranded wire or steel core aluminium stranded wire on the tension pole, used for overhead insulated aluminium conductor and insulating cover. It plays the role of insulation protection.
