Individual conductor wires are extruded in resin before 2- and 3-wire conductors are cabled into a “twist” of conductors before jackets are extruded over them. The jacketing process is similar to insulating copper wires on the extrusion line. The main difference is jacketing uses more extruded resin making it more time-consuming than insulating. Prior to extrusion, talc is applied to the twisted, insulated conductors which acts as a release-agent for stripping the jacket. This is especially user-friendly when a few millimeters of jacket need to be stripped for crimping wires.

Interpower North American and international cable is manufactured in the U.S.A. at its Lamoni, Iowa, facility. So how is Interpower durable and reliable cable manufactured?  

Cable is made up of specialized material and components that are vital parts of making a world-class power cord or cord set. If one of the cable components is damaged, it can directly affect the product. Making sure you know the recommended minimum bend radius for cable is critical to the performance and longevity of your product and its ultimate success.

For those manufacturers who are unfamiliar with North American NFPA 79 requirements, simply finding out they need to meet these requirements for a product they are building or preparing to install can cause a considerable state of confusion. This is especially true for foreign manufacturers importing products into North America and for manufacturers venturing into this product field for the first time or who are installing new equipment from abroad.

A strain relief or cable gland extends cord life and reinforces the cord connection to the equipment. The main purpose is to help protect the electrical connection and circuitry inside the equipment. The most common application is on a power cord providing electricity to equipment. In many situations, the equipment is portable and requires protection so the cable cannot be pulled out of the equipment.
