ELECTRICAL THREAD CONVERSIONS FOR HAZARDOUS AREAS
Company Overview 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.

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.

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.
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.
APPROVALS
The Drain Plug is fitted with an ‘O’ ring as standard ensuring that the IP integrity of the installation is maintained.
Raxton Metallic Drain Plugs are available in a variety of finishes including Nickel, Electro Zinc, Zinc Passivated, Chromatised, Electroless Nickel and Anodised.

Accessories Earth Tags
Raxton Earth Tags provide a means of connecting a flexible earth bond with the gland, thread Adaptor or thread Reducer in any required position whilst ensuring suitable earth continuity. Available in Brass, Aluminium and Stainless Steel and supplied self colour as standard additional plating is available if required.
Screwed Nippling
Supplied 50mm long as standard, alternative lengths can be supplied as required. Available in a variety of thread forms (see page 22). Materials include Brass, Mild Steel, Stainless Steel, Aluminium and Nylon. Metallic finishes can be plated to requirements.
Couplers
Available in round or hexagonal. Manufactured in Brass as standard, they can be supplied with either similar or dissimilar threads at each end in a wide combination of thread forms and sizes.
Bushes
Male and Female Bushes are available in a variety of thread forms (see page 22). Materials include Brass, Mild Steel, Stainless Steel, Aluminium and may be plated to requirements.
Washers
To maintain the IP rating of the equipment Raxton offer a wide variety of entry thread sealing Washers and ‘O’ rings. Materials include Nylon, Teflon, Neoprene, Fibre, and Rubber. In addition Raxton can offer a non setting universal jointing sealant.
Locknuts/Lockrings
Raxton offer a large variety of Locknuts/Lockrings which are often recommended for securing cable glands, thread Adaptors or thread Reducers to a gland plate or into equipment. Locknuts are available in Brass, Mild Steel, Stainless Steel, Aluminium or Nylon.
Shrouds
Raxton offer a range of push on Shrouds which are used to minimise the risk of dirt or foreign substances gathering on the cable gland body and /or point of cable to the gland interface. Supplied as standard in black PVC they are suitable for all leading makes of glands.

APPROVALS
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.
