These premium hard service Type "W" single conductor cables with 400A Camlock connectors are used when double insulated power generation cable is required. These cables are reinforced with an open polyester braid separating the insulation and jacket. This type of construction offers superior mechanical strength, durability and flexibility when compared to standard Stage Lighting Cable.
