Preformed
Loop Detectors are designed for installation into hot asphalt
overlay, concrete overlay, cut-in, or as a temporary above ground
"stick-on" loop detector. Preformed Loop provide cost-effective,
reliable installation in harsh environments.
Application: Preformed
Loop cable has multiple application, e.g. road crossings (with
traffic lights), highways, car parking, traffic counting systems,
speed detection etc.
Features
& Benefits of Preformed Loops: 10-15
year manufacturer 's warranty on Preformed Loops Factory
dimensioned to avoid costly mistakes Factory
assembled for number of turns and wire gauge Wires
protected by high pressure / temperature conduit Entire
conduit injected with water blocking material Faster
installation means increased overall job efficiency Excellent
detection capabilities. Cable
Structure: The
cable will has stranded plain copper conductors of 1.2 mm (7x0.47
mm) nominal cross-section with PVC insulation. Insulated conductors
are twisted in pairs and pairs are individually screened with an aluminum
tape copolymer coated on one side. Under the aluminum tape a tinned
copper earth wire ( of 0.5mm nominal cross-section ) will be
applied. Each pair will be wrapped ( over the screen ) with a synthetic
tape and after all pairs will be stranded together to form the cable
core. The cable core will be wrapped with a synthetic tape and
sheathed with a grey colored PVC compound.
cut-in
Slots. Features: The
detection loop cable is easy to
install,
by choosing a provided by the XLPE insulation. The very
small water-permeability and high insulation-resistance
guarantee reliability and durability by minimizing the
risks of leakage currents to the road surface. Application:
Detection
loop cable has multiple applications, e.g. road crossings (with
traffic lights), highways, car parking, traffic counting systems,
speed detection etc.
