The Resilience of LISTEC

A car fire in the Steinhaus-Taxlberg motorway tunnel led to a major rescue operation on the Innkreis motorway. There was extensive damage to the tunnel walls and also the tunnel electrics- our SEC 20 cable alone survived the fire without loss of functionality. Quality pays off.

Barry Tierney – Project Manager Spie UK commented –

‘Having installed SEC 20 in many tunnels, I have found that if designed and installed correctly it offers excellent service and the integration of the information provided by our specialist SCADA team will assist any tunnel management team to ensure safety is maintained’

Barry also commented what a pleasure it is to work with Cables Britain and how knowledgeable and professional the team are.

CAI re-certification for our Twin Digital Satellite Coaxial Cable!

News

We are delighted to announce that our 2XCB63 has recently passed the CAI benchmark test for the seventh time with the same cable design and manufacturer. This cable is now certified for another 18months and has been regularly tested and passed for a 10 and a half year period! Quite an achievement and the only cable still standing from the start of the benchmark process! First to pass and last original one standing. The test is independently checked and verified with random collection by the CAI. We are proud of this success!

Lynemouth Power Station – Biomass Conveyors

News

Cables Britain Ltd supplied and commissioned a LISTEC system for the biomass conveyors to protect the roller bearings.

LISTEC was employed to provide a fast temperature response in the event of the bearings being overheated, upon receipt of the bearings overheating a signal would be sent direct into the site SCADA system to enable the conveyors to be shut down quickly and reducing the risk of damage to the plant. LISTEC provided a pin point accuracy on the location on the source of heat.

The system was specified by Fairport Engineering and installed by Sir Robert McAlpine.

BDR Renewi Rotherham

News

Cables Britain has recently supplied and commissioned the LISTEC Addressable Heat Detection system to activate the water deluge system on the conveyors in zoned areas.

This was proposed by Marsh Ltd for the waste transfer station to provide an early warning fire detection system on the moving conveyors.

LISTEC was employed due to the fact that the alarm temperature parameters can be freely adjusted to suit the adverse site conditions.

The system at BDR Rotherham was tested and further evaluated by Marsh Ltd.

Ambient Temperature: 30°C
Conductor Operating Temperature: 60°C/85°C
The above table is for 60°C conductor operating temperature is in accordance with T4F1A of the 17th Edition of IEE Wiring Regulations.
** 85°C Table is in accordance with Table 4H2A of the 16th Edition of IEE Wiring Regulations.

The current ratings arranged are for cables in free air but may also be used for cables resting on the surface. If the cable is to be wound on a drum on load the ratings should be reduced in accordance with Note 2 below and for cables which may be covered, see Note 3.

Note 2: Flexible cables wound on reeling drums
The current ratings of cables used on reeling drums are to be reduced by the factors below:

A. Radial Type Drum
-Ventilated: 85%
-Unventilated: 75%

B. Ventilated Cylindrical Type Drum
-1 Layer of cable: 85%
-2 Layer of cable: 65%
-3 Layer of cable: 45%
-4 Layer of cable: 35%

A Radial Type Drum is where spiral layers of cable are accommodated between closely spaced fittings. If fitted with solid flanges the ratings given should be reduced and the drum is described as non-ventilated. If the flanges have suitable apertures the drum is described as ventilated.

A ventilated cylindrical cable drum is where layers of cable are accommodated between widely spaced flanges and the drum and end flanges have suitable ventilating apertures.

3. Where cable may be covered or coiled up whilst on load, or in air movement over the cable restricted, the current rating should be reduced.

It is not possible to specify the amount of reduction but the table of rating factors for reeling drums can be used as a a guide.

Ambient temperature: 40ºC
Conductor operating temperature: 90ºC

Notes
The current-carrying capacities in this appendix are based upon the following reference ambient temperatures:
1. For non-sheathed and sheathed cables in air, regardless of the installation method: 30ºC
2. For buried cables, either directly in the soil or in ducts in the ground: 20ºC

The current rating shown are based on conservative assumptions, and therefore, in some instances, may be adjusted according to the ambient installation and operating conditions.
