What are the benefits of CSPE sheathed cables?
CSPE stands for Chlorosulfonated polyethylene – it is sometimes referred to as CSP.
CSPE is a thermoset, cross-linked insulation and sheathing material with excellent electrical and physical properties. It is typically used as an insulation for cables with a voltage rating up to 600V as well as being a sheathing material for almost any type of cable. It has a wide temperature range from -40°C up to +148°C and can be compounded to achieve even higher temperatures than this.
It is resistant to cold flow - the viscous flow of a solid at ordinary temperatures due to pressure from external loading such as clamping. Other mechanical properties include resistance to impact, abrasion, crushing and chipping. CSPE is regarded as having superior mechanical properties even amongst the other elastomers. Ideal for outdoor use, the sheathing has extremely low water absorption properties, is not effected by ozone, and has very high resistance to ageing by both sunlight and oxidation.
CSPE sheathed cables are favoured in processing plants where airborne chemicals attack ordinary-duty sheathing materials and metal conduits. It is also resistant to hydrocarbons, oils, greases and fuels and exhibits excellent fire resistant properties. It is particularly useful when in contact with oils at elevated temperatures, making it ideal for use in mines and in oil & gas applications.
