SERIES 305 is specifically constructed for light duty applications where size is a critical factor. Single conductors are insulated using a specialized yarn wrapped around the conductors in layers. Yarn is then impregnated to add abrasion resistance and enhance electrical properties. The insulated single conductors are then laid parallel and covered with a layer of braided glass. A final impregnation is applied to the braid.
For higher temperature applications, use SERIES 321.
