INDUCTIVE LOOP DETECTOR CABLES


Inductive loop cable is used to measure and control traffic flow. The cables are buried beneath the road in ‘loops’ and an electrical current is passed through them creating a magnetic inductive field. It is the vehicle passing through this field that creates a disturbance and a means by which to measure traffic flow and vehicle type. Typical applications are for traffic control signals, safety cameras, variable speed control systems, flow monitoring and access control. The cables have to be of a robust design to withstand a hostile working environment and accommodate back filling with hot bitumen.

The three main types of inductive loop cables that we can supply are:

TR2029 issue ‘D’ (NMCS spec.)

1.5mm² tinned copper core, ethylene propylene rubber (EPR) insulated, polychloroprene rubber (PCP) sheathed, 85° rated. Nominal diameter 6.3mm. Suitable for all roads including motorways as approved by the Highways Agency.

FLL1.5EPR/CSP

1.5mm² tinned copper core, ethylene propylene rubber (EPR) insulated, chlorosulphonated polyethylene (CSP) sheathed, 85° rated. Nominal diameter 4.5mm. Suitable for all road applications up to trunk road standard.

FLL1.0EPR/CSP

1.0mm² tinned copper core, ethylene propylene rubber (EPR) insulated, chlorosulphonated polyethylene (CSP) sheathed, 85° rated. Nominal diameter 3.0mm. Suitable for light duty applications such as barrier control and cycle paths or where installation space is at a minimum.

All cables are normally stocked on 1,000m (nom) drums but smaller quantities can be arranged
