Wire & Cable Insulation & Jacket Materials

Galaxy is a leading manufacturer and supplier of standard/stock and custom wire and cable with a wide variety of material choices for the jacket and insulation. The selection of wire/cable insulation material and jacketing compound are critical to the successful use of the wire or cable in its application. Temperature, fire resistance, chemical resistance, UV resistance, durability, and flexibility are important considerations, and the general characteristics of the most commonly used insulation and jacket materials are shown in the table below.

Galaxy works with many customers to assist in the design and engineering of custom cable and wire to help specify the best insulation and jacket materials for specific applications. Whether changing an existing cable or designing a new wire, Galaxy has the knowledge and expertise to provide guidance from design all the way to production.

The wire/cable insulation materials and jacket materials make all the difference in balancing performance and cost. Count on Galaxy to provide expert guidance on selecting the right combination to meet the specifications and environment where the cable will be used, and then getting that cable produced as quickly and economically as possible.
