ACCC, ACSR Twin top tie LJS
ACCC, ACSR Twin top tie, LJS was 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.
Top Tie Twin, LJS are made of high strength corrosion resistant aluminum alloy wire, covered by sand layer and glue, can be used in any environments. Preformed insulator top ties is used for bare aerial bundled conductors in MV and HV power transmission networks. They are intended for smaller line angles than side / spool groove style ties. Additionally equipped with polymer tube, which provide superior holding and electrical performance with best insulation characteristics of applied section.
Helical insulator twin top tie, usually installed on conductor, do not require any tools. Overhead aluminum top tie do not require and protective rods or side splices, it can be installed straight on the HV electrical cable.
The configuration of wire formed top tie is calculated in order to minimize the failure and withhold full rated strength. In addition, our company 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.
Conductor diameter, mm
Thimble, may be applied on tension load
Specified in accordance to cable working load
If the demanded conductor size is missed in following chart, Jera preform line is capable to adjust insulator top tie in accordance to your cable specification, insulator neck diameter and distances between poles. Our entire spiral formed wire products have been tested and verified in order to satisfy the requirements of our customers.
We focus on the quality and complete range of preformed line grips, which includes: ACCC dead ends, dead-end guy grips, grip suspension, side/ spool tie, twin top ties, insulator wraplock ties, armor rods, full splices, thimbles, pole fittings (anchor shackles, ball eye), other formed wire accessories and motion control dampers.
