LCS have a long history of producing DC switchgear, used extensively in safety critical applications for the rail industry. This is exemplified by our extensive list of Network Rail and London Underground approved products. All are comprehensively tested, generally in line with BS EN 50123, with ratings up to 3600V and 5000A. Recently our switchgear has been successfully used in the renewables industry.
We offer a range of services including custom variations of existing products or totally bespoke products. Listed below are some of our popular products.
Negative Short Circuiting Device
The Negative Short Circuit Device 2kA (NSCD) provides a short-circuit path between the DC Traction Supply and the Negative Return to protect against the inadvertent re-energisation of the circuit. The NSCD can be operated remotely via a SCADA Interface, locally via a Local Control Panel and at the NSCD itself for maintenance. The NSCD consists of a motorised 3.2kA Disconnector to provide the short-circuit path, a manual 2.5kA Disconnector to isolate the motorised Disconnector for maintenance, panel lighting and anti-condensation heating, and the associated control equipment. Both Disconnectors are off-load devices so voltage monitoring is included to give indication that the DC Traction Supply is live and to inhibit inadvertent operation of the motorised Disconnector.
CTS Controlled Track Switch
The CTS is a product integral to Safer Faster Isolation Technology, capable of switching and isolation of high power (4000A, 750V) circuits. Often used in conjunction with our NSCD, the CTS isolates the power to the conductor rail, prior to bonding by the NSCD.
The device consists of a fast-acting load break switch and an in line manually operated maintenance disconnector.
ICTS Integrated CTS
The Integrated Controlled Track Switch comprises combinations of previously approved products in a single package pre-wired and tested unit prior to installation.
- 1 x CTS: Controlled Track Switch 4kA – PA05/02035
- 2 x NSCD: Short Circuiting Switch 2.5kA – PA05/06098
The equipment can be fully interlocked to prevent the inadvertent bonding of a live conductor rail.
Tunnel Switch
LCS can provide a number of switches/disconnectors suitable for deep tunnel applications. Compact size enables these devices to be fitted to tunnel walls and operated via remote control cabinets. On load and off load, single and double pole options are available.
LCS2 Track Disconnector
The LCS2 is an off load 4000A manually operated track isolation disconnector. Used extensively to provide a point of isolation to allow safe working the track. The equipment is housed in an IP56 GRP enclosure. The operating handle can be padlocked in the open or closed position and can be further protected via mechanical, key operated interlocks
Combiner
Suitable for use on large battery installations, the combiner panel provides a point of isolation between the incoming supply and the battery banks. Additional fuses can be provided to protect against short circuits.
OS Load break switch
The OS load break switch is a fast acting manually independent spring-operated switch. Capable of making on short circuit currents of 65kA and breaking currents of 15kA. It is available as 900V or 1800V rated voltage options
The switch is equipped with high performance double break contacts and separate current carrying and current breaking contacts
The insulation is ultra-low smoke material that is approved for use in the London Underground.
Left hand, right hand and double pole options are available.
OD Off load disconnector
The OS load break switch is a fast acting manually independent spring-operated disconnector. Capable of making on short circuit currents of 65kA it is available as 900V or 1800V rated voltage options.
The switch is equipped with high performance double break contacts.
The insulation is ultra-low smoke material that is approved for use in the London Underground.
Left hand, right hand and double pole options are available.
