In many applications, equipment is located far from the nearest power outlet. A safe and reliable way is required to extend power supply to the equipment. Our Specialty extension cords are designed for this purpose. They are manufactured as a continuous one-piece construction without intermediate splices or joints. Spliced connections may create potential risks such as overheating, arcing, or leakage current. The one-piece structure eliminates these risks and improves overall power transmission safety and reliability.

Built for Long-Distance Power Delivery

For long cable runs, conductor material and design are critical factors. We use high-purity oxygen-free copper conductors to ensure low electrical resistance and reduced heat generation during operation. Copper conductors provide significantly lower voltage drop compared to aluminum or copper-clad aluminum alternatives, ensuring stable voltage delivery to connected equipment.
Insulation materials include high-quality PVC or XLPE, offering excellent dielectric strength and aging resistance. The outer jacket is designed with enhanced thickness for improved abrasion resistance and mechanical durability, making it suitable for workshop environments, industrial floors, and temporary outdoor installations.
Shielded versions are available to reduce electromagnetic interference generated during long-distance power transmission. Each extension cord is fully tested for continuity and dielectric strength before shipment. Our products comply with IEC 60227 standards and are CE certified.
Custom length options are fully supported, ranging from short patch cords to continuous lengths exceeding 100 meters. Jacket colors can be customized for circuit identification, and length marking can be printed on the cable surface for easier installation and maintenance. Standard sizes are available from stock, while custom configurations have short production lead times.
