About insulators
Electrical insulators hold live conductors in place while keeping current from flowing into poles, towers and structures. Types include porcelain and glass disc insulators, pin and post insulators, and composite or polymer insulators with a fibreglass core and silicone rubber housing and sheds. Silicone polymer designs are light, resist pollution and vandalism, and shed water well, which suits coastal and industrial areas. Buyers compare system voltage, mechanical failing load, creepage distance, shed profile, end fitting type and compliance with IS or IEC standards, for distribution lines, substations and railway electrification.
