| Adaptor |
Adaptors provide a means of connection between dissimilar thread forms or sizes. |
| Armour |
Mechanical protection usually accomplished by a metallic layer of tape, braid or served wires. Normally found only over the outer sheath. |
| Armoured Cables |
Armoured cables are used to transfer power overhead or underground. The armoured cable is constructed of 2 – 4 inner cores of cable which are individually sheathed. These are then covered in a plastic sheath, which is covered in a wire metal armour, and then a final outer layer. Armoured cable is used to ensure the cable cannot be accidentally broken, and the wire metal armour is earthed as an extra precaution. |
| Braid |
A fibrous or metallic group of filaments interwoven in cylindrical form to form a covering over one or more wires. |
| Cable |
A group of individually insulated conductors twisted helically. |
| Cable Core |
A cable core is the portion of an insulated cable lying under the protective covering or coverings. |
| Cable Glands |
Cable glands are made of metal (such as brass or stainless steel) or nylon. Cable glands are used to firmly secure electrical cable entering a piece of equipment, and provide a seal between the external and internal surfaces of the equipment. |

| Clamp |
A clamp is a fastening device to hold or secure objects tightly together to prevent movement or separation through the application of inward pressure. |

| Cold Flow |
Any permanent deformation due to pressure or mechanical force, without the aid of eat softening |
| Connectors |
An electrical connector is a conductive device for joining electrical circuits together. The connection may be temporary, as for portable equipment, or may require a tool for assembly and removal, or may be a permanent electrical joint between two wires or devices. |
| Control Cable |
A term describing any cable which carries control signals or protocols between electrical or electronic devices. This signal can be as simple as a low voltage analogue signal or as complex as a bi-directional digital protocol. Increasingly, performance electronics are utilizing computer ether-net protocols over thin-net, or fibre-optic network cables. |
| Core |
Any portion of a cable over which some other cable component, such as a shield, jacket, sheath or armour, is applied. |
| Elastomer |
A material that at room temperature returns rapidly to approximately its initial dimensions and shape after substantial deformation by a weak stress and release of the stress. |
| Flame Resistance |
The ability of a burning material to extinguish its own flame, once its flame-initiating heat source is removed. |
| Flame Retardance |
Ability of a material to prevent the spread of combustion by a low rate of travel so the flame will not be conveyed. |
| Neoprene |
A rubber-like compound used for jacketing where wire and cable will be subject to rough usage, moisture, oil, greases, solvents and chemicals. |
| Nitrile Rubber |
A rubbery copolymer of butadiene and acrylonitrile. It is usually compounded and vulcanized. |
| Polyvinyl Chloride (PVC) |
A thermoplastic material composed of polymers of vinyl chloride, which may be rigid or elastomeric, depending on specific formulation. |
| Power Cable |
A power cable is an assembly of two or more electrical conductors, usually held together with an overall sheath. The assembly is used for transmission of electrical power. Power cables may be installed as permanent wiring within buildings, buried in the ground, run overhead, or exposed. Flexible power cables are used for portable and mobile tools and machinery |
| Reducer |
Reducers effectively reduce the threaded entry diameter of an enclosure to accept a gland or fitting with a smaller thread. |
| Sheath |
The material, usually an extruded plastic or Elastomer, applied outermost to a wire or cable. Very often referred to as a jacket, or an impervious metal covering usually lead. |
| Terminal |
A terminal is a conductive device for joining electrical circuits together. The connection may be temporary, as for portable equipment, or may require a tool for assembly and removal, or may be a permanent electrical joint between two wires or devices. |
