NP-INDIA cap & pedestal type post insulators are designed mainly to support disconnecting switches, busbars, conductors and equipment of substations. They are capable of being stressed in tension, compression, flexing, torsion and combined stresses upto the specified limits. These insulators are more economical than other types of insulators used for similar applications. Cap & Pedestal type post insulators are divided into two main groups, viz. non-stacking and stacking units. For service voltage upto 33 kV single units are available. Multi-unit stacks are available for service voltage up-to 145 kV.
