ECCOH™ Low Smoke and Fume Non-Halogen Formulation 5983 With high environmental stress cracking resistance for power cable jacketing The new ECCOH™ 5983 formulation helps prevent environmental stress cracking in low and medium-voltage armored power cables, helping to prevent costly cable damage and disrupted power supply. The ECCOH 5983 formulation has been developed to help prevent stress cracking in armored cables by offering high tear strength and elongation at break at temperatures ranging from -25°C to 90°C. The new formulation surpasses all specifications associated with the BS 7655-6.1:1997 standard, including the most stringent LTS1 classification, even for complex designs and armored cables.
