Combating Galvanic Corrosion at CMP
The type and thickness of nickel coatings applied to brass cable glands varies significantly around the world, and many of the solutions adopted are inherently porous, meaning that they are unable to provide complete protection against chemical attack, corrosion, or material break-down. There are typically two types of nickel plating in common use, these being electro nickel plating and electro-less nickel plating.

The DTS:01 Test Specification was developed by Shell UK in conjunction with ERA Technology, based in Leatherhead, Surrey. Since its inception in 1991 it has been widely accepted by all major offshore operating companies as the standard to meet with respect to deluge protection.
Read moreCable Gland Sizing – Cable Construction & Armour Wires
Cable glands conforming to British Standard BS 6121:1973 were specifically to cater for industry standard armour wire sizes and cable diameters found in British and international standard cables. These armour wire sizes have remained common to virtually all cables manufactured to BS, IEC and AS/NZS standards, and can be accommodated by some industrial cable glands to BS 6121 & IEC 62444 and explosive atmosphere certified cable glands to IEC 60079. There is an expectation that within a given armoured cable, all of the armour wires have the same consistent thickness so that cable glands utilising a cone and clamping ring can be correctly terminated and maintain their safety critical functional performance. If the armour wires in an armoured cable have significant differences in their thicknesses then it may be no surprise if consequent issues arise with their termination when using standard products. The correlation between the cable inner bedding diameter and the cable armour wire is clearly defined in IEC 60502-1 and AS/NZS 5000.1.
