Medium Voltage MCS



This is the so-called factory assembled and type-tested indoor type 24kV metal-clad swithgear, assembled under rigorous quality control and passed the careful verification tests.

It is designed to accomodate high-performance vacuum circuit breaker which has been designed and manufactured in accordance with IEC56 and BS531, the switchgear itself conforms to IEC298 and B5227, and all primary components used therein are in accordance with the relevant IEC and/or BS standards.

The modern production process has been introduced for the manufacture of main components, primarily in sheet-metal forming, the technique of joining frameworks, insulator of main busbars and surface protection. We inform various operators of the fact that our switchgear technology assures an enormously wide range of applications and the higest possible operational reliability.


  1. Metal Clad type
  2. Box Type Compartment (non Metal)
  3. Cubicle Type
  4. Small Box Compartment
  5. Partition Index - Low Protection
  6. Non Partition


The cubicle framework is constructed of pre-fabricated steel plates which are riveted / welded together to form a rigid enclosure. The cubicle construction is fully metalclad as defined in IEC 298 (BS 5227).

Internally the switchgear cubicle is partitioned to provide separate compartments for :

  • Busbar
  • Circuit breaker
  • Cable sealing end
  • Auxiliary equipment (optional)

Each compartment except the auxiliary equipment compartment which houses low voltage equipment is provided with a pressure relief flap.

The standard degree of ingress protection for the cubicle is IP31, as defined in IEC 144, while for the partition is IP2X. Other standard features include :

  • Fixed covers which can only be opened with the aid of tools
  • Anti condensation heater in circuit breaker and cable sealing end compartment
  • Earthing conductor within the cubicle
  • Front door with lock
  • Multicore cable box at rear of cubicle


The busbar are fabricated from high conductivity copper and are coated with epoxy or heat shrink material to provide good insulation.

Potentian Transformer

PTs connected to the circuit side are placed at the rear of the cubicle sealing end compartment. Fixed mounted PTs with swing out primary fuse for isolation (standard) a separate potential transformer cubicle with truck mounted PTs can also be supplied.

Earthing Switch

Where required, the switchgear is provided with a fault making integral earthing switch. It is designed, manufactured and tested in accordance with IEC 129. The earthing switch can be operated from the front of the switchgear with the use of a handle and is interlocked mechanically with the circuit breaker.

Safety Shutters

Each safety shutter covering the busbars and circuit contacts can be operated individually. To fasilitate testing each shutter can be latched in the open position without padlocking and subsequently released into the closed position.

The shutter mechanism is designed so as to be operated by the movement of the circuit breaker to ensure automatic opening and closing of the shutters.


The switchgear has provisions for padlocking in the following positions :

  1. A circuit breaker truck in the service and isolated (testing) positions
  2. Mechanical operating knob of the circuit breaker (optional)
  3. Safety shutters in the closed position
  4. The earthing switch operating handle in the closed or open position

Operation tools

Each switchboard is provided with the following tools :

  • VCB spring charging handle
  • Earth switch operating handle
  • VCB truck draw-out handle (optional)
  • VCB elevating handle (double busbar switchgear only)


Vacuum circuit breaker model VJ 22 has been designed and type tested in accordance with IEC 56 BS 5311. The circuit breaker is truck maunted with rollers for easy movement. The truck is earthed in the service, isolated (test) and intermediary positions via earthing contacts.

Control and indicating devices are located on the front of the circuit breaker unit. These include manual close / open knob, manual charging slot, position switch, operation counter, close / open indicator, spring charged and discharged indicator. The component contained in INDUSCLAD 2001 are manufactured and tested in accordance with their relevant standard specifications.

Interlocking systems

The switchgear is provided with mechanical interlocks to prevent :

  1. A closed circuit-breaker being withdrawn from or inserted into the service position
  2. A circuit-breaker being inserted into the service position unless auxiliary circuit plug is connected
  3. A control circuit plug being disconnected unless circuit-breaker is in the isolated (test) position
  4. The closing of a circuit-breaker unless it is in the service or isolated (test) position
  5. Tripping by attempted isolation
  6. Closing of feeder earthing switch unless the circuit-breaker is in the isolated (test) or removed position
  7. A circuit-breaker from being inserted into the servce position unless the feeder earthing switch is open
  8. A circuit-breaker from being closed unless the closing spring is fully charged

Interlocking system for circuit breaker insertion / withdrawal


The individual switchgear units are assembled together wired up, tested, and delivered with the VCB truck inserted. The busbars are supplied separately for transport reasons, The cable connecting space of the switchgear is designed so that commercial cables,suitable for the rated feeder current, can be employed to connect the switchgear. Heat shrinkable cable terminations can be accommodated with in the switchgear. The switchgear room should have the following minimum size.


The INDUSCLAD 2001 is safe and simple to maintain, if work has to be carried out on particular parts of the switchgear, these parts should, of course, first be switched off and earthed. As the INDUSCLAD 2001 has fixed fault making type earthing switches, operating and maintenance personnel are protected at a maximum safety.

Technical Specification

Notes :*1According to the standard "IEC-298 and 694" the relations "temperature to humidity" are as follows :


                *2Dimension shown here indicated that of standard type (main busbar rating of 1250A)


Notes :*1XM, XE and XEM of the closing operating system are conformed to close 1,15 of ESI standard 41-26 (operating mechanism)

                        XM : Manually-charged spring with manual release

                        XE : Manually-charged spring with manual and electrical release

                        XEM : Motor-charged spring with manual and electrical release
