The Olflex® SDP TC Severe Duty Power cable, or simply SDP TC, is a Bus Drop approval cable that has some unique features that it has when compared to other Olflex® cables. One of those is the orange elastometric alloy jacket that covers the wiring. This elastometric alloy jacket is also TC-ER approved passing all UL standards that run for 600 volts. This means that you can apply this kind of cable for both commercial and industrial conditions, in cold and other hazardous environments, for control and/or power applications, and even for machine tools or in the electrical circuitry of factory installations. The heavy-duty wire, aside from being approved for 600 volts, is also approved for use in 1000 volts.
This cable goes has still more unique features compared to other motor supply cables. The finer stranding that it has gives it a little more edge. Its wire is also covered with pressure extruded jackets that make this cable a very flexible property for installation. The design of this wire also conforms to NOM and CE standards that make it a globally acceptable solution for wiring.
The construction of this wire is made of finely stranded tinned copper wires. These wires are then covered PVC or nylon insulations, which makes it a little different to other Olflex® cables which are covered with the special formulation of Lapp Surge Guard®. This, however, does not decrease the efficiency of this wire as it compensates with barrier tapes and a specially formulated elastometric alloy jacket.
This jacket makes this wire highly resistant against oil and other chemical intrusions that can cause damages or decrease in conductivity. Aside from the oil and chemical-resistant version, submersible pump approvals are also available in special orders. The Olflex® SDP TC Severe Duty Power cable is highly resistant against heat, though it could only burn or melt when exposed to extremely high temperatures. On the other hand, it is not very flexible so it is not really recommended for electrical machineries that require perpetual motion. However, this wire scores very high when it comes to toughness and mechanical rigidity.
The minimum bending radius for installing this wire is rated at 7.5 times the diameter of the cable. For example, if you have this wire in 26 awg, then you can multiply it by 7.5 to get the minimum bending radius for a 26 awg Olflex® SDP TC. This wire can work for temperatures as low as -40°C to even temperatures beyond 150°C. The nominal voltage that you can use this wire can be in 600-volts (based on UL-TC) or in 1000-volts (based on UL AWM), yet its test voltage can reach to even up to 4000 volts. Like other Olflex® cables, the Olflex® SDP TC Severe Duty Power cable can also be used for variable frequency drives of VFD’s. Yet at the same time, unlike other VFD cables, this one can also be used for non-linear power distortions that can be sometimes associated with other VFD’s.
