Heavy Wall Flex Glass is engineered from a high quality braided fiberglass sleeve surrounded by a heavy silicone rubber coating. SGH expands slightly for easy installation, and is tough and flexible enough for use in tight radius applications. The silicone coating will expand and flex without cracks or fractures, and the treated fiberglass minimizes end fray and dusting during assembly and use. Heavy Wall Flex Glass resists dielectric breakdown caused by operational stresses. SGH is highly abrasion resistant and remains flexible in low temperature applications. It is also resistant to common chemicals, inorganic acids, alkalis and alphatic hydrocarbons. Rated to 392°F. (Class H), SGH is in extensive use in dry-type transformer applications, and is ideal for terminal insulation and protection in a wide range of operating environments. Heavy Wall Flex Glass is available in Red.
