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.

Combustible dust can be ignited by electrical equipment in several ways, for example by: - Surfaces of the equipment that are above the minimum ignition temperature of the dust concerned. - The temperature at which a type of dust ignites is a function of the properties of the dust;
Read moreCommon Cable Gland Types Designed to IEC Standards
Under IEC standards, three main types of cable glands exist for braided, armoured and non-armoured cable intended for use in explosive atmosphere applications.
