Wires for power supply connections to frequency converters

NEW! Increased Maximum Conductor Operating Temperature: +90 °C

HELUKABEL, a leading international manufacturer and supplier of cables and wires, announced at the SPS IPC Drives in Nuremberg two new motor connection cables – the TOPFLEX-EMV-UV-3Plus 2XSLCYK-J and the TOPFLEX-EMV-UV-2XSLCYK-J – which have conductor temperature resistances of 90°C.

Both cables are suited for supplying power to frequency converters while ensuring electromagnetic compatibility (EMC) in systems, buildings and facilities from devices and operating equipment which can emanate electromagnetic interference and cause impermissible impact.

A higher current load rating is possible due to the improved conductor temperature resistance of 90°C. Therefore, a smaller cross section compared to standard cables can be chosen when designing the electrical network of a machine or system. In addition to the resulting lower costs and use of copper, the much smaller outer diameter offers advantages for installation in tight spaces.

Both cables are designed for medium mechanical loads in both fixed and occasional flexing installation in wet rooms or outdoors. They are suitable for use in the automotive, food and packaging industries, in environment technology, washing machines, handling devices, pumps, fans, conveyor belts and air conditioning devices. Their use in explosive environments is also possible.

Both cable families, the choice of which depends on the connection equipment that is selected, are self-extinguishing and flame retardant in compliance with DIN VDE 0482-332-1-2 and DIN EN 60332-1-2. They are UV resistant and have a low operating capacity. The low transfer impedance results in good electromagnetic compatibility. The materials used are free of silicone, cadmium and substances harmful to the wetting properties of lacquers.
