this #R757 ignition cable the ultimate in RFI (Radio Frequency
Interference) suppressing, 7 millimeter, silicone-insulated ignition
cable. We have evaluated all of those RFI-reduction (either by attenuation or by suppression) ignition cables designed principally for vehicular applications and have not found them durable enough for industrial applications. But the spiral-wound, stainless-steel, suppressing conductor of our new R757 cable, when properly terminated, meets the durability requirements of the continuous-duty, severe service, spark-ignited gas engine. We recommend that this style ignition cable be used only with termination configurations where there is a screw thread connection at both sides of the secondary circuit. This is because the tensile pull strength of this single strand of fine gauge stainless steel wire does not equal the tensile pull strength of our #757 multi-strand, copper conductor, ignition cable. With the more conventional, automotive-oriented ignition arrangement, it is typical for an oilfield mechanic to pull the cable termination off the spark plug at the spark plug change interval by yanking on the ignition cable. Though this is not a recommended practice, our copper conductor ignition cable will withstand this disconnection method far longer than any RFI-suppressing cable. With the RFI-suppressing style of cable, a single instance of this yanking can break the conductor. With that fragility in mind, we recommend that the operator specify our factory assembled, ESL2 series safety-shielded secondary leads. And only when that requirement of RFI suppression is specified. For ESL2 series secondary leads that are available, please see the product listings ESL2 Safety-Shielded Secondary Leads. |
