Oil resistant for cable

Cables demonstrating various degrees of oil resistance are specified for use in a number of applications such as railways, shipbuilding, offshore platforms and wind turbines. 

Often the most difficult performance parameter for the cable sheath is the retention of mechanical properties after immersion in IRM902 and IRM903 oils at elevated temperatures.  Standards for offshore drilling rigs may also require resistance to oil drilling muds which can be more demanding in this respect.  Cables used in these applications also have the added difficulty of having to be installed and to operate in very cold climates.

Some typical standards are;
     BS7655-1.4 2000      Insulation and sheathing for cable elastomeric cables
     BS7655-1.5 2000      Insulation and sheathing for cables - coil end leads
       BS7655 2.0 2000       Sheathing compounds for ships wiring and offshore applications
     BS7655 2.6 1997      Ordinary duty oil resisting types
     EN50305 2002       Railway rolling stock cables - thin wall
     EN50264-1       Railway rolling stock cables - standard wall
     IEC 60092-359      Sheathing materials for shipboard power and telecom cables


These types of cable are usually made using rubber as the sheathing and insulation.  However, there are a number of companies who are keen to enter this market who do not have the use of the continuous vulcanisation (CV) line necessary to cure the rubber.  In addition, even in those companies that have this technology, there can be a shortage of capacity and it is expensive to install more.
