NIM caps are applied for aluminum and copper stranded wires.
They are intended for a sealed multicore.
Admitted mechanical stress on the crimped connection for carrying wires makes up: – 1200 N for cables of 16 and 25 mm2 in section; – 2500 N for cross-sections of 35, 50, 54, 70 and 95 mm2.
NIM caps are applied for aluminum and copper stranded wires.
Wire crimping should be done from the center edgeward complying with the crimping border and number of crimpings indicated on the device.
The wire should be inserted into the device until bumping.
Insulation thickness should be maintained at on the same level up to the stripping line.
Stripping border should be flat.
The required stripping length is indicated on the bushing.
To attain these ratings, it is necessary to strip the correspondent insulation layer from the wire.
The bushing construction provides for ensuring tightness of 6 kW (50 Hz frequency) for 1 min at a depth of 1 meter.
Polymer insulating material is resistant to UV and weather conditions.
Inner chamber of aluminum part is filled with couplant protecting the aluminum surface from corrosion, lowering the contact resistance that contributes to reducing electric losses as well as ensuring a stable electric contact the within copper-aluminum system that protects the connection point from contact electrochemical corrosion.
Each wire size is shown with the help of a colored sealing ring.
Intended for a sealed multicore cables termination by means of crimping.
