Disk insulator is designed to link together into strings, typically of two or more, to provide much higher voltage protection than any single insulator and used on high tension power transmission towers.

Disk insulator introduction:
Applicable Standard: IEC, ANSI, BS, AS, DIN, GB and specified by customers.
Ceramic Disk insulators are certified by international laboratories such as CESI in Italy and EPRI in China
Porcelain is by far the most commonly used insulating material but there are a number of glass styles as well.
Mechanical strength up to 530kN
High reliability through accumulated technology
Excellent long-term performance
Available for any voltage and contamination level by changing number of insulators

Porcelain disk insulator revolutionized the power distribution industry allowing much higher voltage protection -- there are several 1,000kV DC transmission lines utilizing porcelain disk insulators.
