surges and transients, such as lightning. The compound can be used for both land and subsea cables. In addition to delivering the important conductive properties for monitoring and electrical functionalities, Dow Endurance DHDA-7708 BK also delivers excellent protective characteristics required for jacketing over MV, HV and EHV power cables. It provides the mechanical strength and durability of a normal insulating jacket. Compared to conventional thermoplastic semiconductive mat- erials, this compound is said to offer improved environmental stress-crack resistance, better thermomechanical and low-temperature properties (flexibility in colder climates), easier strippability and stronger cut-through and abrasion resistance. The compound also offers reduced moisture vapour transmission and adhesion to strippable insulation shield while reducing system cost at time of installation and over the cable lifetime.

All sites are certified according to IS/ TS 16949 and ISO 14001 and utilise the Suzuki Garphyttan Lean system. Garphyttan products are commonly used in automotive applications, but high performance and quality makes them suitable for very many different and varied applications.

Dow Endurance™ DHDA-7708 BK is appropriate for medium, high and extra-high voltage (MV, HV, EHV) applications and can be applied as a thin layer over an existing jacketing grade during manufacture or as a cable jacket extruded entirely of this semiconducting compound. The compound provides a reliable earth (ground) continuity path to allow integrity testing of the cable jacket, either upon installation or years later. The material can be used in any situation where graphite has traditionally been used, but is a particularly good choice where cables are installed in air, for example in duct systems or tunnels or where ground conditions make testing graphite- coated cables difficult. Unlike graphite, Dow Endurance DHDA-7708 BK resists being washed and abraded from the surface of the cable during installation and over years of service. When used as the sole jacketing material, Dow Endurance DHDA-7708 BK provides continuous earthing (grounding) along the entire cable. This affords additional protection from Suzuki Garphyttan Group is a producer of valve spring wire, said to have around one-third of the worldwide market. The Suzuki Garphyttan Group provides high quality spring wire products globally from its three sites in Sweden, the US and China. All three sites produce valve spring wire for the automotive industry. Other products include oil tempered wire for transmissions while special wire products, such as stainless spring wire and flat/shaped wire, are produced in Garphyttan, Sweden.
