The 11kV polymer disc insulator is made of high-quality hydrophobic silicone rubber, which exhibits excellent resistance to pollution flashover and maintains electrical insulation performance under harsh environmental conditions. The inherent waterproof (hydrophobic) properties of the silicone rubb
Product Detail
The 11kV suspension polymer insulator is designed to provide reliable insulation and mechanical support for conductors in medium-voltage overhead distribution systems. It is widely used in 11kV power transmission lines, utility pole lines, and rural electrification projects.
Compared with conventional porcelain or glass insulators, polymer suspension insulators are manufactured using a fiberglass reinforced epoxy core rod, high-quality silicone rubber housing, and corrosion-resistant metal fittings, forming a lightweight and durable structure. This advanced design ensures excellent electrical insulation performance and mechanical strength while significantly reducing installation and maintenance costs.
Due to its outstanding hydrophobicity, pollution resistance, and weather resistance, the 11kV suspension polymer insulator performs reliably even in harsh environments such as coastal regions, industrial areas, and high-humidity climates.
The internal core rod is made of high-strength fiberglass reinforced epoxy resin, which provides excellent tensile strength and load-bearing capacity. This structure ensures the insulator can withstand conductor tension, wind load, and other mechanical stresses.
The outer housing is made from high-temperature vulcanized (HTV) silicone rubber. This material offers strong hydrophobic properties that prevent the formation of conductive water films on the insulator surface, reducing the risk of leakage current and flashover.
The end fittings are typically made from hot-dip galvanized forged steel, providing excellent corrosion resistance and strong mechanical connection with transmission hardware.
The silicone rubber housing provides reliable insulation performance and reduces the risk of flashover in polluted environments.
Polymer suspension insulators are much lighter than porcelain insulators, which simplifies transportation and installation on overhead lines.
The hydrophobic surface of silicone rubber ensures stable insulation performance even under contamination such as salt fog, dust, and industrial pollutants.
The fiberglass core rod provides excellent tensile strength, ensuring stable operation under heavy conductor loads and adverse weather conditions.
Polymer insulators are highly resistant to UV radiation, ozone, and temperature changes, ensuring reliable performance for many years.
The 11kV suspension polymer insulator is commonly used in:
Medium-voltage overhead distribution lines
Utility pole line systems
Power substations
Rural electrification networks
Industrial power distribution systems
Its strong resistance to pollution and weather makes it suitable for coastal areas, industrial zones, and regions with severe environmental conditions.
