About UsCompany Profile

Polymer insulator is a type of insulator used in power systems to support and insulate high-voltage conductors. Unlike traditional porcelain or glass insulators, polymer insulators are made of high-quality silicone rubber or other polymer materials and have excellent mechanical and electrical properties. These insulators are designed to withstand harsh environmental conditions such as extreme temperatures, UV radiation and pollution while providing reliable insulation and support for overhead power lines.

silicone rubber insulator is a advanced polymer insulator designed to electrically isolate and provide mechanical support for overhead power lines, substations, and other high-voltage applications. Representing a significant leap from traditional porcelain or glass, silicone rubber insulators leverage the unique properties of silicone elastomers to deliver unparalleled reliability in challenging environments. They are the preferred choice for modern, resilient electrical grids worldwide.

A lightning arrester is an overvoltage protector, mainly used to safeguard various electrical equipment (including transformers, switches, capacitors, mutual inductors, generators, motors, power cables, etc.) in power systems, railway electrification systems, and communication systems from damage caused by atmospheric overvoltage, operating overvoltage, and power frequency transient overvoltage. It serves as the foundation for insulation coordination in power systems.

Lightning arresters serve as the core first-line defense in electrical protection, dedicated to shielding high-power industrial equipment from lightning strikes and power surges. By providing a low-impedance discharge path, they swiftly divert excess electrical energy to the ground, effectively avoiding equipment failure, data loss and fire hazards caused by overvoltage, thus ensuring the stable operation of industrial electrical systems.

surge arrester, often called a lightning arrester, is a critical component of any modern electrical protection system. Its primary function is to safeguard electrical equipment, such as transformers, switchgear, and substations, from damaging voltage spikes and transient overvoltages.
