Panel Manufacturing Facility
Opened in 2007 MJBI operates a panel manufacturing facility for the assembly and testing of control panels. Our technicians are fully skilled in control panel manufacture and are complimented by a design team with many years of experience in this industry.
All panels are built to the highest British and European standards and quality is assured through our ISO 9001:2000 quality procedures. We provide solutions to your panel requirements over a range of industries including power generation, process plants, water treatment and many others and can range from assembly only, to complete turnkey package of design, manufacture, installation and commissioning.
Turbine Control Panel
Our turbine control panel (Sentinel) is designed using PLC technology at its core, and with a built in conditioning monitoring package (Tiger) it offers great value for money as a replacement gas turbine control system for old and outdated controllers.
Sentinel is offered in a range of options either as a single processor simplex design or as a dual redundant hot standby system with a choice of PLC's from Allen Bradley, Siemens S7 or Fanuc. All configuration software is designed and written by our own engineers and no third party contract resources are used.
Motor Control Centres
We offer a range of MCC designs to suit our individual customer's requirements from modular (column) design with either fixed or withdrawable drawers suitable for AC or DC use, to back to back type where space is a prime consideration.
All panels are ASTA and KEMA tested, and the enclosures are designed and tested to the latest standards, from BS5486 to BS EN 60439-1 and now BS EN 61439-2 (IEC 61439-2)
General panel construction for the column design is extendible fully welded IP54 outer frame unit columns manufactured from 2.5mm Zintec prime quality sheet steel, providing exceptional strength and rigidity.
All busbars are manufactured from hard drawn high conductivity copper, fully supported in insulated support system. Busbars are optionally tinned and/or insulated (sleeve wrapped). Standard Busbar design clearance is 25mm with minimum accepted 20mm (Phase to Phase and Phase to Earth).
Connections to busbars on withdrawable units are via substantially rated plugs and sockets. The socket part is connected directly to the busbars. A high level of segregation between different parts of the enclosure is a standard feature of all systems, especially where withdrawable units are connected to busbars through a high integrity shutter system which is mechanically activated and can also be padlocked.
Control and indication units are located on the front of withdrawable starter trays, mounted on a removable instrument plate. Various combinations of control/indication units can be accommodated depending on compartment size.
Generator Control/Protection/Auxiliary Panels
Generator control and protection panels are manufactured to suit a wide range of generator application ranging from 1MW to several hundred MW and house automatic voltage regulators (AVR) and generator protection relays. Control and indication of generator output is via switches and indication mounted on the front door.
Auxiliary panels are built to house a variety of sub-systems such as fire and gas and vibration monitoring and protection systems such as Bently Nevada.
