Atex Certified Insulated Adaptors - (AI-D Series)

Redapt AI-D Series of Insulated Adaptors provide a method of insulating a cable gland and the cable armour from the equipment into which it has been fixed.

Insulated Adaptor AID

Insulated Adaptors provide a vital safety precaution for systems with sensitive electronic equipment that are reliant on an interference free power supply.

Manufactured from hexagon material to facilitate easy installation, they incorporate a glass filled nylon dielectric insulator between the metallic male thread entering the equipment and the metallic female thread receiving the cable gland.

They may also be used for matching electrical threadforms on hazardous area approved equipment whilst ensuring the integrity and Ex approval of the installation is maintained.

CSA Approval 1248014 (LR 106084-2)

Redapt Insulated Adaptors are designed for hazardous area applications and are certified to protection concept Exd “Flameproof” for use in Zone 1 and Zone 2 applications.

Approved to the latest international standards, insulated adaptors can be supplied with GOST-R hazardous area certificates.

In addition CSA approval certificates can be supplied to cover use in North American and Canadian Class I Division 2 and Class I Zone 1 applications.


Application
To avoid relying on the contact between cable termination and equipment enclosure for grounding the cable armour, an insulated adaptor can be fitted to both ends of the cable with a grounding device (i.e. earth tag/lug) fitted between the adaptor and the termination. The armour current can then be taken from the grounding device to ground in a controlled, positive manner that can be inspected easily.

Single point grounding
In many applications it is sufficient to ground the cable armour at one end. For single point grounding, the insulated adaptors would again be used at both ends of the cable but with the earth tag fitted only to the end where grounding
is required.

Single point grounding can:
• Reduce the circulating currents that can cause heating of high capacity cables.
• Reduce the risk of damage to electronic equipment within the enclosure in the event of a short circuit to ground through the enclosure.
• Reduce the problems of electrical noise on the armour affecting the clean earth required for some sensitiveinstruments.
