OKGT-s cable

Fiber optic cable incorporated in ground wire OKGT-s for suspension on overhead power line support with voltage 110 kV and higher.

Application:

Сable is designed for suspension on overhead power line support with voltage 110 kV and higher. It performs two functions: to transmit information and to protect the phase conductors from a lightning strike, which may damage the transmission system.
