3dc Sensor Cable
Insulated solid copper wires with a diameter of 1 mm and area of 0.75mm2
Electric resistance on 1000 meter of wire at 20 ° C is approximately 25Ω
Installed directly on the tape / media pipe surface
Wire joints are made by crimping on a metal sleeve using crimping pliers
Outer casing of polyethylene
Diffusion barrier of aluminum foil Polyurethane insulation foam
3dc wire used for leak detection with protection tape
Pipe made of steel, copper & HDPE.
Functions:
- Minimizes condense problems in pipes and fittings
- Fast installation in the production stage
- More than 170.000 m delivered
- Can be used to both steel– and plastic pipes
- Easy to assemble and connect in the field
- Constant distances between wires in the cable
- Facilitates fault detection in fields
- At the production of district cooling pipes and fittings,the WiDetect 3dc cable is assembled directly close to the media pipe. Also, in field joints, the cable shall be located directly against the media pipe. We recommend reading the 3dc user manual before mounting starts.
- The special design of the cable permits that impedance changes from wet insulation, of a certain size, can be detected, although the cable is insulated along the whole cable length.
- Max measuring length with X3 is 3000 meters.
- The outer conductors(red/red) forma loop and the water measurement is done against the middle conductor (black). Connecting of cables in a T- branch. This item is prefabricated. Cable length: main pipe 2 x 2 m, branch pipe 3 m.
