Conductor Pulleys for String Three Bundle Conductor Line

The anti twisting steel wire rope's manufacturing principle is to use a group of left-handed and right-handed single-strand round wire ropes, and weave them according to a certain pattern.

An A-Shape lattice gin pole is a temporary, engineered lifting frame used to raise, position and install poles, towers, and associated equipment during transmission-line, telecom and utility structure erection. Unlike single-tube or tubular gin poles, the A-shape lattice design uses an open, triangulated frame that combines high strength, low weight and torsional stiffness. This configuration makes it particularly well suited to lifting and up-ending whole tower sections, antenna assemblies, crossarms and similar components where controlled, guided lifting and a compact on-site footprint are required. Manufacturers commonly offer A-shape lattice gin poles in aluminum-alloy and high-tensile steel variants to balance portability, strength and corrosion resistance.

Universal Stringing Blocks are precision-engineered mechanical devices used for stringing conductors, ground wires, or optical fiber cables during power line construction and maintenance. Their main purpose is to support and guide conductors efficiently while minimizing friction and mechanical stress. In modern grid infrastructure, the use of high-tensile materials and long-span transmission lines demands robust, adaptable, and safe stringing equipment — and Universal Stringing Blocks play a crucial role in achieving this balance.

Ningbo Lingkai Electric Power Equipment Co., Ltd. is a leading manufacturer and supplier of Cable Pulling Rollers.

The double capstan winch is an important industrial equipment with a wide range of applications. It is also used for pulling wire rope for tower erection and lifting goods on tower.

​We've been where you are. At Ningbo Lingkai Electric Power Equipment, our team spent years working transmission line projects before we started building equipment. That field experience is why our overhead line stringing equipment works differently.
