Keywords Cables,Corrosion, Remora Electrical
It is reported that where corrosion from chemicals or outdoor installations is a problem, positive ingress protection for PVC single wire armoured PVC cable gland terminations can be achieved with the CCG corrosion guard from Remora Electrical Ltd of Sheffield(Plate 6).
The corrosion guard is claimed to be impervious to most chemicals and offers IP68 level of protection. It prevents water damage to the steel wire armour of cables, as well as chemical attack to the metal of the cable gland itself from acids and otherwise corrosive atmospheres.

Manufactured from black self-coloured GRP material, the corrosion guard can be supplied complete with CCG type BW or D1W captive cone glands which are fitted with special outer nuts incorporating a male thread extension to lock the guard into position. The BW gland is designed specifically for indoor use, but the type D1W, which incorporates an additional internal seal, can be used in hazardous areas and is EExe rated.
A total of seven corrosion guard assemblies can be supplied in the BW range covering cable outer sheath diameters from 11.5 to 78mm, with corresponding inner sheath diameters from 12.6 to 68mm. There are eight sizes in the D1W range covering from 16 to 78mm outer and 6 to 68mm inner sheath diameters.
These glands both feature the well established advantage of a freely rotating captive cone, which provides an armour clamp and earth bond without detrimental twisting of the wire armouring.
Fitting is said to be simplicity itself with the two guard components first slipped onto the cable. The gland is then fitted and the cable terminated in the normal way. The guard body is then screwed onto the gland, creating a positive bullhead seal against a polypropylene gasket also supplied. The corrosion guard nut is then tightened onto the body, creating a positive barrier against dust and fluids ingress.
