Flameproof Insulated Adaptors

Adaptors | Flameproof & Increased Safety

Raxton Exd hazardous area insulated adaptors provide a means to isolate the earth of the supply cable from the load equipment thus reducing the risk of damage to electronic equipment within the enclosure in the event of a short circuit to ground through the enclosure. – adaptors are ATEX Certified.

Insulated Exd adaptors, manufactured by Raxton, also reduce the problems of electrical noise on the armour affecting the clean earth required by some sensitive instruments. Single point grounding can reduce the circulating current that can cause heating of high capacity cables.

Cable gland and cable can still be earthed externally with the use of an earth tag fitted between the cable gland and the insulated adaptor.

Raxton flameproof (Exd) insulated adaptors are marked with the applicable approval number and size.
