HELUKABEL, one of the leading cable manufacturers, has added two new motor connection cables to its TOPFLEX product family: the TOPFLEX-EMV-UV-3 PLUS 2XSLCYK-J and the TOPFLEX-EMV-UV-2XSLCYK-J – which have conductor temperature resistances of 90°C.
A higher current load rating is possible due to the improved conductor temperature resistance of 90°C. This enables a smaller cross section compared to standard cables to be used when designing electrical networks in machines or systems. In addition to the resulting lower costs and use of copper, the much smaller outer diameter offers advantages for installation in tight spaces due to an increase in the cable‘s maximum bending radius.
The TOPFLEX-EMV-UV-3 PLUS 2XSLCYK-J is constructed using a three conductor plus three symmetrical ground configuration for improved concentricity and creating an electrically “balanced” cable. It is available in sizes 16 AWG to 500 kcmil. The TOPFLEX-EMV-UV-2XSLCYK-J uses a traditional three conductor plus full-size ground structure and comes in sizes 16 AWG to 350 kcmil. 
The latest TOPFLEX cable products are jacketed using a special PVC compound, double shielded and use XLPE insulation on the inner conductors, which makes them ideal for applications that experience high voltage spikes and have long cable runs due to their low capacitance.
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 malfunctions.
They are both 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 TOPFLEX products are UV resistant, self-extinguishing and flame retardant in compliance with DIN VDE 0482-332-1-2 and DIN EN 60332-1-2. 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.
