The popular 8DJH series of 11/22 kV switchgear has a bigger brother – the 8DJH-36.
This range of switchgear is physically a slightly larger, scaled-up version of the very successful 8DJH RMU's. In terms of front panel design and operation, it’s hard to tell the difference between the two ranges, thus saving the need for further operator training. An outdoor enclosure is also available.
The 8DJH-36 is 36 kV rated (20 kA 3 sec) with a bus current rating of 630 A. The range includes:
- Ring switches
- Cable to bus panels
- Transformer fused T-offs
- Circuit breakers
- Air insulated billing/metering panels – arc rated (with option for cable connection left, right or both)
- Bus section
- Ability for VT’s to be mounted in the switchgear panel – a special extra panel for VT’s is not required
- Automation for remote control – including earth switches if desired
Suitable for indoor applications such as power distribution systems, energy supply of utilities or larger industrial sites, the 8DJH-36 range includes several predefined, lower cost, single SF6 gas block configurations. It’s also versatile with the option to allow future extensions of panels to left or right.
The 8DJH-36 is being used for outdoor to indoor conversion of 33 kV switching stations locally in New Zealand, and is planned for use on mobile substations. For many of New Zealand’s smaller substations, where a 630 A rating is sufficient, 8DJH-36 offers considerable saving in capital cost compared to traditional primary switchgear.
