24 KV Metal Clad Cubicle is an indoor, metal-clad switchgear unit intended for the MV section of HV/MV subtations and high power MV/MV substations. 24 KV Metal Clad Cubicle adapts to all electrical power distribution requirements from 1 to 17,5 kV.
24 KV Metal Clad Cubicle switchboards are made up of several interconnected functional units. Power connections are made between functional units within a switchboard via a single busbar. The electrical continuity of all metal frames is provided by the connection of each functional unit's earthing busbar to the switchboard's main earthing circuit. Low voltage wiring trays are provided in the switchboard above the low voltage control cabinets. LV cables can enter the switchboard through the top or bottom of each functional unit. A functional unit comprises all equipment in the main and auxiliary circuits which together provide a protection function. Each functional unit combines all the components which are required to fulfill this function: The cubicle, the protection, monitoring and control system and the withdrawable part.
36 KV Metal Clad Cubicle is metal-enclosed switchgear with withdrawable units designed for indoor installation. It is designed for the MV section of HV/MV substations and high-power MV/MV substations. 36 KV Metal Clad Cubicle is suitable for all electrical power distribution requirements from 1 to 40,5 kV.
36 KV Metal Clad Cubicle switchboards are made up of several interconnected functional units. A single busbar is used to connect the power between functional units within a switchboard. The permanent electrical continuity of all the metal frames is provided by connecting the earthing busbar of each functional unit to the main earthning circuit of the switchborad. Low voltage wiring trays run across the switchboard above the LV compartments. LV cables can enter the switchboard through the top or bottom of each functional unit.
A functional unit comprises all the protective main and auxiliary circuit equipment. Each functional unit combines all the components required to fulfill its function: The cubicle, the protection, monitoring and control system and the withdrawable part.
A MV power supply interruption is unacceptable especially in critical applications, because of this an automatic system is required for MV source transfer. 24 KV Ring Main Unit is enables automatic control and management of power sources in your medium voltage secondary distribution network with a short transfer time(less than 10rnseconds), guaranteeing the hi-reliability of your installation.
Compact self-contained totally insulated switchgear
- Comprises 1 to 4 integrated, low dimensions functional units
- Choice of transformer feeder protection: circuit breaker with self powered protection unit or switch disconnector combination combined with fuses.
- On site extensibility for nextwork enhancement
- Electrical command for telecontrol
- Monitoring and alarms of events
24 KV Ring Main Unit is protecting people and goods allrnover the world with 1.000.000 installed functions in MV secondary underground distribution applications. 24 KV Ring Main Unit is a functional unit designed to meet the operating and enhancement requirements of power distribution Networks. Safety of supply, continuity of service and insensitivity to the environment. 24 KV Ring Main Unit is the choice for hi-reliability. It can be adapted to meet all medium voltage power distribution needs up to 24 kV.
36 KV Metal Enclosed Cubicle units are used for the MV section in MV/LV transformer substations in public distribution system and MV consumer or distribution substations from 10 kV to 36 kV.
36 KV Metal Enclosed Cubicle units are designed for indoor installations(IP3X).
Their compact dimensions are:
. 750 mm to 1500 mm width
. 2250 mm height
. 1400 mm depth
That makes for easy installation in small rooms or prefabricated substations. Cables are connected via the front.
All control functions are centralised on a front plate, thus simplifying operation. The units may be equipped with a number of accessories (relays, toroids, instrument transformers, low power current transformers (with Sepam only) , surge arrester, telecontrol, etc.)
Ringmaster unit has the solutionrnfor all medium voltage applications, such as simple transformer protection,rnsectionalising with remote control to multi- panel metered consumer switchboards.
Quality engineering for extreme climates enables Ringmaster unit to provide flexibility for any locations. Covering a wide range of options with an indoor and outdoor IP54 design and ratings up to 13.8 kV, 630A and 21 kA, Ringmaster unit has proved successful in markets around the world. Simple,rnclear operation combined with compact size, high functionality and reliability extends the applications of the Ringmaster unit range.
The key feastures of Ringmaster unitrnare following:
- Gas pressure indicator as standard
- Anti-reflex operating handle with facilities for electrical operation
- Interlocked medium voltage cable test access
- Earth screened cast-resin gas module
- Range of dry type metering units-
- Mechanical tripped on-fault indication
- Simplernto follow mimic providing user-friendly operation
- Resin encapsulated busbars in air bus chamber for extensible version
- Direct coupling to transformers or cable connection
A variety of different panel types are available for each unit within the range, together with a number of optional accessories, enabling Ringmaster unit to satisfy the most complex system specification.
Ringmaster unit helps you control and monitor your network to the self-powered VIP relay, that optimises your network protection against phase and earth faults. Alternatively, you combine communication and protection to benefit the hi-reliability of a device that provides:
Very sensitive earth fault protection
Cold load pick-up
