Top ties are designed to match the head, neck of polymer insulators, porcelain insulator, post-type insulators to conductor applied, from the top side of insulator. Insulator top tie is used for bare aerial bundled conductors in MV and HV power transmission networks. Tie top for polymer insulator are made of aluminum covered steel, aluminum materials. Material of heliformed top ties depends on material type of conductor to be applied with, ACCC or ACSR. Preformed tie top insulator additionally equipped with ribbon rube to decrease abrasion of conductor and insulator.
Jera’s produce wire formed insulator top ties of the following types: top tie wraplock, top tie twin (double support tie). Both kind of helical top ties provide an improved method of securing cable, compared to hand tie over line protector rods
The unique, one-piece design without any bolts or high-stress holding devices guarantee easy installation with long life period of preformed insulator top ties.
Jera is capable to develop preformed tension grips and preformed top ties according to your cable specification, insulator neck diameter and distances between poles.
We are focus on the quality and on the completed solutions for our customers.
