Insulators

For electrical safety and functionality

OPTEC has expanded its range of insulators to meet customer requirements. We now offer a wide range of insulators and their supports. We offer the entire range from stock. Insulators or support insulators are used in all systems in which offset spacer masses are necessary or prescribed. However, aspects such as safety and functionality are also rational decision criteria for our SK type insulators.
