PAD MOUNT Isolator
CELSA provides full support to ENTEC's pad mount-type isolator in its three-phase model, designed for application in underground lines for voltage classes up to 15 kV and 27 kV, with the combination of Circuit Breaker (CB) and Load Break Switch (SW).

The CB is operated by a permanent magnetic actuator with a vacuum switch for arc suppression. The SW is operated by a spring lever mechanism that provides independent closing and quick opening operation
The bushings are made of HCEP (Hydrophobic Cycloaliphatic Epoxy) which provide excellent insulation performance even in adverse climate environments and polluted areas. The epoxy molding structure allows for easier maintenance.
Two types of microprocessor-based controls can be applied for automatic operation: ETR102/104, which is a dual protection relay for measurement and monitoring, and ETCCU104, which has integrated RTU with communication, measurement, monitoring and logging functions. The switching equipment has been fully tested by a KERI-accredited laboratory in accordance with an ANSI 37.60 international standard and the KEPCO specification and is RETIE certified.
