China Manufacturer 11kv 33kv Ball and Socket Disc Suspension Porcelain Insulator
Suspension insulators are designed to link together into strings, typically of two or more, to provide much higher voltage protection than any single insulator. Suspension insulators are typically used on high tension power transmission towers as shown below. Porcelain is by far the most commonly used insulating material but there are a number of glass styles as well. Porcelain suspension insulators revolutionized the power distribution industry allowing much higher voltage protection -- there are several 1,000kV DC transmission lines utilizing suspension insulators.
Available for any voltage and contamination level by changing number of insulators
Mechanical strength up to 530kN
High reliability through accumulated technology
Excellent long-term performance
