Raxton Limited have been manufacturers of Electrical Thread Adaptors, Reducers, Stopping Plugs and accessories since 1976. Today Raxton remain committed to products designed to solve the fundamental difficulties which exist due to the variety of thread forms currently in use within the electrical industry.

Problems caused by dissimilar threads can occur in both hazardous and industrial environments. Raxton products are fully approved to meet these requirements, being EExd and EExe certified as ATEX, CSA, IECE and GOST Standards.

Many products such as Cable Glands, Drain Plugs, Insulating and Earth devices have been added over the years. Raxton now has a worldwide distribution base for its extensive range.

Experience shows that our customers are unable to cope with extended deliveries. We recognise the need to respond quickly and have established a reputation throughout the industry for prompt despatch of orders, however large or small.

Raxton will continue to offer, alongside its standard range, a bespoke and specials manufacturing service to meet the needs of the market it serves.

Whilst the company continues to expand and develop, Raxton’s principal objective will always be to maintain its high standards of customer satisfaction.

Raxton 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. Insulated Adaptors 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 Insulated Adaptors are marked with the appropriate approval number and size.

The Raxton Exd Breather/Drain Plug is designed to: 1) effectively drain moisture from an enclosure, 2) allow air from the enclosure to vent into the surrounding atmosphere thereby minimising moisture build up and 3) provide the explosionproof safety required by a hazardous area environment.

The Plug is fastened to the lowest point of the enclosure by means of a spanner.

The plug is an assembled item and must not be taken apart at any stage of installation.

The 'O' ring will seal against the enclosure face enhancing the I.P. rating of the Plug.

The Breather/Drain Plug has an impact resistance of 20 Nm and can operate at temperatures between -50°c to +230°c

Tested to IP66

Raxton EExe Drain Plugs effectively drain any moisture build-up present within the enclosure whilst allowing air in the enclosure to breathe with the surrounding atmosphere minimising moisture build up within the enclosure.

Fastened by means of an allen key the Drain Plug should be fitted at the lowest point of the enclosure.

The Drain Plug can be fitted:

a) into a chamfered plain hole using drainage washer and locknut or castellated locknut on the inside of the enclosure.

b) directly into a threaded hole provided that, if the thread protrudes, the drainage hole is visible.

The Drain Plug can be supplied with either a serrated washer and locknut allowing the condensation to drain whilst ensuring the Plug is shakeproof or with a castellated locknut.

The Drain Plug is fitted with an ‘O’ ring as standard ensuring that the IP integrity of the installation is maintained.

Raxton Compound Stopper Box is designed to seal conductors at the entry to the enclosure via conduit or to enable an existing compression gland to be converted to a barrier gland. This is achieved by forming a barrier between the individual insulated conductors within the cable to prevent an explosion within the enclosure. The Compound Stopper Box allows compound to be packed around individual insulated conductors. Assembly of the component compresses the packing material and distributes the compound evenly to effect a barrier at point of entry into the enclosure.

The Compound Stopper Box is supplied with compound in a pack, complete with making off instructions and gloves.

Raxton Compound Stopper Box is marked with the appropriate approval number and size.

*in some countries the methods of protection a & q are allowed in Zone 1.

tEMpErAturE ClASSExplosion protected electrical apparatus must be designed and tested to ensure that the maximum surface temperature of any part(s) of the products are below the ignition temperature of the explosive atmosphere concerned. Group II electrical apparatus is divided into temperature classes according to the maximum permissible surface temperature of the apparatus. The preferable classification of temperatures is given in the following table:-

Unless otherwise specified the maximum ambient temperature is taken to be 400ºC.

ZOnE 1 21 Zone in which an explosive atmosphere is likely to occur in normal operation. (Rough guide: hazard present between 10 & 1000 hours/year).

ZOnE 2 22Zone in which an explosive atmosphere is not likely to occur in normal operation and if it occurs it will exist only for a short time. (Rough guide: hazard present for less than 10 hours/year). Guidance in the classification of hazardous areas is given in BS EN 60079-10:1996, IEC79-10.
