S & C indoor and outdoor distribution insulators

S & C indoor and outdoor distribution insulators include outdoor station post insulator, indoor apparatus insulator, switch pushrod, switch strut and standoff insulators etc.

S & C indoor and outdoor distribution insulators

S & C indoor and outdoor distribution insulators can be made of porcelain and silicone rubber materials. Porcelain insulators traditionally have been the most widely applied insulators in electrical transmission and distribution systems.

Porcelain distribution insulators have several drawbacks which include brittleness, low impact strength, relatively high weight, and substantial limitations in manufacturing flexibility. Nowadays, light-weight non-porcelain insulators or polymer insulators have gained increasingly wide usage in application formerly provided with porcelain insulators.

The first application of polymer materials for electrical insulation was used in the manufacture of indoor switch and bus insulators. With the insulator manufacturing process developing, outdoor usage of polymer materials for electrical distribution insulators are used widely in electrical systems.

S & C indoor and outdoor distribution insulators are normally composed of metal end cap and porcelain units, or silicone rubber housing and sheds used with switch.

Polymer distribution insulators can used outside indicated a sensitivity to ultraviolet radiation in sunlight, as well as susceptibility to tracking in contaminated environments. S & C indoor and outdoor distribution insulators are manufactured of composite materials having lightweight, good contamination performance and high electrical and mechanical properties.
