Type of insulators in high voltage

Type of insulators in high voltage is divided into suspension insulator, line post insulator, crossarm insulators, station post insulators and transformer bushings used for electrical systems or equipment.

Type of insulators in high voltage

According to insulator application, Type of insulators in high voltage has
◆ High voltage transmission line insulators
◆ High voltage post insulators
◆ High voltage bushing insulators
◆ High voltage stay insulators etc.

The features of Station post insulators
◆ Designed in extra high voltage, ultra high voltage
◆ Available as multi component versions
◆ Made from porcelain or polymer

The characteristics of suspension insulators
◆ High voltage power transmission line insulators
◆ Used for any voltage overhead power lines
◆ Flexible used
◆ Porcelain material used in suspension, also called suspension disc insulator
◆ 33kv disc insulator is normally replacement the 33kv pin insulator made from porcelain

The features of stay insulator
◆ Widely used where the tension load of conductor is higher
◆ Most important factor of strain insulator is a mechanical strength
◆ Widely use where high mechanical strength is necessary in low voltage applications

Type of insulators in high voltage or in transmission line is not same. High voltage station post insulator is normally used in substations for supporting and insulating.
