NL Preformed Ground Wire Tension Set

NL series pre twisted strain clamps are used for the installation of bare conductor or overhead insulated conductor of power transmission and distribution lines.The reliability and economy of the products are better than those of bolt type,wedge type and hydraulic type strain clamps widely used in current lines.There are many kinds of pre twisted strain clamps,which can be divided into pre twisted conductor strain clamps,pre twisted stay wire strain clamps,etc.It can replace the UT clamp and wedge clamp which are commonly used to fix the stay wire on the road pole and tower in China.The structural design of the pre twisted strain clamp is very simple.The legs of the pre twisted strain clamp are twisted to form an empty pipe,and the rear part is a pre formed hinge ring.When the legs of the pre twisted strain clamp are wound on the conductor or stay wire,it can produce strong grip force,and the hinge ring is used to fix on the insulating porcelain or tower or ground anchor.The unique principle and structure make the performance of pre twisted tension clamp unique and distinctive.
