General Specification of the Water Terminal

The terminal suit for Power cable’s delivery test, type test and qualification test.

The terminal is designed for indoor use.

The terminal consists of 2 sets terminal tubes and one deionizer water condition unit.

The terminal suitable for 500kV and below XLPE power cable testing

Remote control is available.

Rated voltage of the terminal reaches 800kV.

Before operating, please make sure every unit are safety earthing.

Terminal is removable, convenient for testing.

Deionizer resin can be replaced on-site.

Water storing case has four tubes for water-in and water-out

There are emergency button, user can press it when emergency situation to keep safety.

Electric sensor can supervise the temperature, pressure, flow velocity and water electrical conductivity.

Sensor supply 4-20mA signal to feed programmable processor, the operation mode will display on the control panel.
