HarcoSemco: Materials that last

HarcoSemco’s static harnesses are designed for resilience in the toughest of applications. In order to protect the critical wiring components from exposure to harsh environmental conditions, HarcoSemco offers connector over molding utilizing various polyurethanes and fluoreolastomers. The abrasion resistant jackets or outer coatings are available in Teflon, Nomex, PEEK or Stainless Steel.

Through custom material selection and detailed design of components, HarcoSemco engineers have developed harnesses to meet all durability demands, whilst maintaining the lightest possible weight. In-house braiding of the EMI shielding coupled with innovative termination processes ensure the best in class protection for signal protection.

Electrical harnesses

HarcoSemco custom-designed electrical harnesses offer packagers, operators and suppliers of GE LM Series gas turbines, reliable, cost effective solutions for the most demanding industrial and marine applications. Designed, tested and approved for installation in hazardous locations, all HarcoSemco harnesses are ATEX & UL/CSA listed.

Offering both on and off-engine application for the LM Series turbines, Harco harness assemblies utilize stainless steel connector/back shell configurations and incorporate rubber over-molding at the cable transitions. Coupled with EMI shielding techniques, flexible cable lay-ups and abrasion-resistant, machine-applied braid applications, the HarcoSemco GE LM Electrical harnesses are well suited for the harsh environments typical of the installation.
