Applications
We specially developed this guillotine hand shear to solve two specific problems with low and medium temperature self-regulating cables:
- The difficulty of cutting the carbon filled polyethylene heating zone between the 2 bus wires.
- The obligation to maintain a mandatory insulation distance between the bus wires of these heating cables when they are connected to a terminal block or to one cable end seal. This minimum insulation distance depends on the use of
the cable: in an industrial environment in a non-explosive atmosphere, this distance can range from 2 to 3.6mm depending on the materials. In an industrial environment and explosive atmosphere, using a type EX “e” connection, this minimal distance is 5mm. (See standards EN60079-7 and EN60947).
This tool allows to cut easily the polyethylene matrixto respect these distances in all cases.
Main features
According to the different models of the different manufacturers of self-regulating heating cables, the distance between the bus wires is highly variable, ranging from 1.5 to 4.2mm.
Jaws:
Notch length: 5mm for each manual cutting operation.
Notch width: They exist in three configurations, allowing to cover the different spacings between existing between bus wires.
- Cables with distance between bus wires from 1.5 to 2 mm.
- Cables with distance between bus wires from 2 to 3.3 mm.
- Cables with distance between bus wires from 3.3 to 4.2mm.
This last model also allows cutting cables and conductors according to type 4 and 5 cuts.
Production of special pliers: Possible on request, send us cable samples.
Each guillotine notching plier is delivered in a professional box with a set of cable dimension guides
