In applications where cables may be subjected to attack from oils, solvents, gases or other chemicals, designers and installers of critical cabling systems have historically relied upon using conventional lead-sheathed cable to provide maximum protection. However, the use of lead sheathed cable is often unsatisfactory due to its weight, large bending radius and cost. For applications prone to hydrocarbon attack and moisture penetration, especially relevant to the on-shore oil, gas and petrochemical industries, Hydrocarbon Resistance Cables are a new generation of non-permeable cables, utilizing a combination of modern materials allied to novel production techniques.
