In the field of power system construction and upgrading, High Voltage Polymer Hollow Composite Insulator Price Concessions has become a key concern for global buyers. This type of insulator offers excellent electrical insulation, high strength, and superior anti-pollution flashover performance, making it widely used in substations, switchgear, and GIS equipment.
The high voltage polymer hollow composite insulator is made of an epoxy fiberglass rod as the core, with a high-grade silicone rubber sheath. It is manufactured using advanced integrated molding technology, offering a superior alternative to traditional porcelain insulators, especially in seismic-prone and harsh environments.
Core Rod: High-strength epoxy fiberglass rod
Sheath Material: UV-resistant silicone rubber
Flange: Hot-dip galvanized steel or stainless steel
Seal: Epoxy resin sealing, excellent airtightness
