Post insulator top tiesare used for bare, and insulated aerial bundled conductors in MV and HV power transmission networks。
Preformed insulator top tie, usually installed on conductor, do not require any tools. Polymer top tie do not require and protective rods or side splices, it can be installed straight on the HV. It developed to secure the aluminum (ACC), aluminum alloy (ACCC), aluminum covered steel reinforced (ACSR) conductors to top of groove of the polymer insulators, porcelain insulator, post-type insulators

Components and materials
Preformed top tie wraplock, are made of dielectric PVC wire, which may be used in any environments. They are intended for smaller line angles than side / spool groove style ties. Insulation tube is covering the center of wraplock top tie. That provide superior holding and electrical performance with best insulation characteristics of applied section.

Test
The configuration of wire formed top tie is calculated in order to minimize the failure and withhold full rated strength. In addition, Jera Line has researched plenty of varieties of aluminum top ties that is why we are able to match our wire formed ties to your aluminum conductor size.
If the demanded conductor size is missed, we are capable to adjust insulator top tie in accordance to your cable specification, insulator neck diameter and distances between poles. Our entire preformed line products have been tested and verified in order to satisfy the requirements of our customers.
