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 matrix to 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
