Precise Electric Manufacturing Company Limited
PEM can manufacture suspension insulators with an outer layer of silicone rubber as the insulating material. It can be used in 15kV, 24kV, and 36kV systems. The product was designed to be used in all weather conditions and can be used in highly contaminated areas.
Precise’s Suspension Insulators can be divided into 3 types;
- Type PS-R041-CE for 15 kV system
- Type PS-P061-CE for 24 kV system
- Type PS-P101-CE for 36 kV system
Silicone Housing Suspension Insulators For 15 kV system up to 36 kV system
