APPLICATIONS
TECHNOFLEX 3Plus 2XSLCH-J and TECHNOFLEX 3Plus 2XSLCHK-J shielded halogen free cables with symmetrical construction are intended for connecting converters or inverters with motors in industrial installations, production plants, air-conditioners and other equipment operating in dry and wet locations.
Small mutual capacitance and higher, up to 90°C, operating temperature limit of conductors is offered due to application of cross-linked polyethylene insulation.
Cables are protected by a specially designed and highly effective collective shield against emission of electromagnetic interferences to environment and against influence of external interferences.
The division of the protective conductor into 3 evenly distributed in the cable core (on the circumference of 120°) enabled to achieve a symmetrical distribution of fields and reduce the emission of electromagnetic interference into the environment in relation to the cables with four conductors.
Halogen free cables, applied when higher safety in case of fire is required. The cables are flame retardant, their smoke emission in fire is low and released gases are not corrosive.
TECHNOFLEX 3Plus 2XSLCH-J cables are suitable for indoor and TECHNOFLEX 3Plus 2XSLCHK-J cables for outdoor fixed and movable installations.
