FZSW High Voltage Polymer Post Insulator is a composite station post insulator designed for medium-voltage distribution systems, substations, switchgear, and outdoor electrical equipment.<\/p>\n

Constructed with a fiberglass reinforced epoxy (FRP) core rod, HTV silicone rubber housing, and hot-dip galvanized metal fittings, it provides excellent electrical insulation, high mechanical strength, and superior performance in polluted and harsh environments.<\/p>\n

 <\/p>\n

Features<\/strong><\/h2>\n

1. The silicone rubber housing taken shape by whole injection. It has good hydrophobicity, hydrophobicity migration and soil resistance, as well as excellent electrical insulation properties and aging resistance, which could prevent effectively those accidents of pollution flashover so as to ensure the safe running of high voltage transmission lines.<\/p>\n

2. The modified ECR fiberglass reinforced epoxy resin rod is used as it has good resistance to high temperature, stess corrosion & acid attack, as well as fine damping action, high tensile strength (> 1200Mpa) and resistance to creep and fatigue failure, which effectively ensure the internal insulation quality and mechanical stength of insulators.<\/p>\n

3. End fittings are crimped onto fiberglass rod with voice-operated displacement type crimper. The insulators with this crimping technique have high mechanical strength and small dispersion. Taking the most advanced automatic overall injection moulding technic and connection method of crimping for production and assembling, and the whole crimping procedure controlled by computer and the crimping result monitored by ultrasonic detector to assure each product is qualified.<\/p>\n
