■BYPASS SYSTEM

BYPASS SYSTEM is installed on the overhead distribution line to make a temporary “bypass” circuit for maintenance work, such as replacement of pole, wire, transformer and switches, without planned outage or for emergency response / recovery in case of the natural disasters.

❚ Flexible work methods and configurations

“Flexibility” is the advantage of using our BYPASS SYSTEM. Our BYPASS SYSTEM can be adapted to various sites by using a combination of equipment. The equipment configuration is determined by the customer's request such as construction environment, purpose, and pole-to-pole span. In case there are little vehicles and passersby, bypass cable can be placed on the ground.

❚ Easy to Handle

The pole mounting of the BYPASS SWITCH is completed in simple steps:

1. Wrap the chain around the pole to fix the mounting bracket.

2. Lift the BYPASS SWITCH up to the install position and hook on the bracket.

BYPASS SWITCH can be installed on any types of poles (round or square). Also, our BYPASS SWITCH is very lightweight and easy to carry.

❚ Our BYPASS SYSTEM is consist of One-touch connection

BYPASS SYSTEM uses special equipment and cables with one-touch connections which allow easy connection and disconnection. Because of its usage and purpose, BYPASS SWITCH bushings, Bypass Cable connectors, and Joint connectors are suitable for the repeated connection and disconnection, and Bypass Cables does not need any cable termination.

❚ Reliable Phase Checking Feature

BYPASS SWITCH has the feature of phase checking. Phase Checking Device at the bottom of BYPASS SWITCH emits sounds and signals (LED) to show the status of cable connection of each phase whether they are connected correctly, open phase or out-of-phase. By using this feature, you can check not only the cables are connected correctly but also applied voltage to the cables and preventing short-circuit fault before closing the switch.
