Medium Voltage Switchgear Panels
• VCB/SF6 Panels up to 40kA for both Indoor & Outdoor Applications
• Double Bus bar Panels with Grid & Standby power supply bus bars with
(a)mechanical and electrical interlocks for single bus bar supply and
(b) Synchronizing system for load sharing by grid and stand by supply
• Skid mounted/ Containerized Breaker Panels
Medium voltage air insulated load break switch in sheet steel enclosure is suitable for either Indoor or Outdoor installation as transformer incomer on HV side. The switch opening and closing operations are spring assisted for quick make and break of the load current and no-load charging current of the transformer. Auto-trip protection on short circuit or earth fault by HT Fuse/s (if provided) operated by integral pop up buttons on the fuses and remote trip or relay trip on load or on fault by trip coil are possible as optional features.
SF6 insulated Ring Main Unit (RMU) for secondary distribution networks that utilizes the latest developments in switchgear technology to provide a smart, safe and compact fuse protected Ring Main system. Safe Plus is a completely sealed system with a stainless steel tank containing all the live parts and switching functions. A sealed steel tank with constant atmospheric conditions ensures a high level of reliability as well as personnel safety and virtually a maintenance-free system. Options of a Switch Fuse combination or a Circuit Breaker with protection relay in place of the switch fuse for the transformer are available.
A Package Substation is completely self-contained Solution for power distribution that includes outdoor duty enclosure, medium voltage switchgear, distribution transformer, low voltage panel, and accessories such as power factor improvement equipment, control and protection equipments, all providing a cost effective and efficient total self contained installation.
It finds extensive application in small industry, building and power distribution units.
Factory assembled weatherproof solution ready for placing into position and only incoming and outgoing cables need to be connected.
A variation of the above is a Containerized Substation where the enclosure is a container to facilitate easy lifting and shifting; these are specially useful for open mines, quarries etc.
Vacuum Contactor Starter panels are suitable for controlling electrical apparatus in industry such as motors, and other equipment like transformers with supply voltages up to 11kV. They are also used in power factor correction capacitor banks switching systems.
