ENTK-R

ENTK-R Ring network cabinet

Product overview:

Ensafe series entk-r ring network cabinet is a compact environment-friendly gas insulated metal enclosed switchgear with up to 6 circuits in a common box or multi unit expansion. The voltage level is 12 ~ 24kV, the maximum rated current is 1250A, and the short-time withstand current is 25kA. It shall be applied to ring network or radial power supply lines as incoming / outgoing / circuit section / line branch and load switching / circuit breaker protection switchgear.

Product features:

Three station, miniaturization

The load switch uses a three station mechanism with fast rotating air blowing and arc suppression, which has three positions of "opening", "closing" and "grounding". The number of parts is small and no maintenance is required. The circuit breaker adopts vacuum arc extinguishing, with compact overall structure, spring operating mechanism, corrosion-resistant layer, bearing self-lubricating and small operating power.

High reliability and long mechanical life

The mechanical life of load switch is up to 5000 times and that of circuit breaker is 10000 times

Fully enclosed, fully insulated

With the characteristics of fully enclosed / fully insulated, the whole switchgear is not affected by the environment and can be installed in places where moisture, sand dust, salt fog, mines, box transformers and air pollution are easy to cause surface pollution flashover;

Low leakage rate and long service life

The O-ring is adopted. All high-voltage electrified bodies are sealed in the gas insulated gas box. The fully enclosed cable plug connection is adopted. The protection grade reaches IP67 to eliminate the hidden danger of air leakage.

intelligent

Meet the requirements of distribution network automation, adapt to the requirements of distribution network automation and power supply reliability, have three remote functions, and use remote control unit (FTU) to realize remote operation status and fault monitoring / remote operation of main components.
