The structure of the armour guarantees maximum resistance to crushing, cutting, and wear. The armoured wire has higher tensile loads.

The aluminium wire armour (AWA) and steel wire armour (SWA) provide the mechanical protection. Why are armoured cables used?įor outdoor installation or direct burial applications, there is a need of mechanical protection of electrical cables. The armour made of aluminium wires placed under the sheath to protect the conductor, and insulate the layers. The armoured cable has an extra protective layer to keep it away from unwanted cut or damage. The armour provides the ultimate protection against electrostatic, magnetic, and common modes. It also avoids waste because the armoured cable are available in continuous rolls of convenient length. There is no need of rigid conduit pipe, such as threading, bending, making support when we use armored cable. Installation of armoured cable is fast and economical. It also prevents any internal irregularities from causing the release of dangerous energy levels to the outside in environments.Īrmoured cables are insulated with non-flame propagating thermoplastic compounds with low emission of smoke and toxic gases, covered with metal armour. The external vulnerable force to cables are rodents, and accidental impacts. Socket Female Gearmount Coupler (STD.An armoured cable has a metallic layer of strips, or threads that protect the conductors from external forces. Plug Male Line Coupler (STD.) (QUIK) (1/4-TURN) Threads Plug Make Gearmount Coupler (STD.) (QUIK) (1/4-TURN) Threads

All additional options are available for the above coupler. Male/Female assemblies are interchangeable within housings. For further safeguard, optional electrical and mechanical (key type) systems are available. Positive thread engagement of the metal housing prevents accidental disconnecting and insures proper opening and closing sequence. Tight fittings covers for plug and socket, protect contacts and insulators from moisture when disconnected. Thorough gasketing makes the coupler entirely watertight. Housings are of rugged, corrosion resistant cast aluminum providing high strength with light weight.

Adalet PLM Cable Couplers provide safe, convenient means for connecting portable cable rated up to 15,000 volt and up to 500 Amperes, copper or aluminum conductor to mining equipment, electric shovels, draglines, loaders, bargers, tunneling machines, portable substations, portable junction boxes, or for joining lengths of high voltage cables. UseĬouplers are utilized in underground, strip, and pit operations on every continent in the world, and for coal and hard rock mining operations of every type. The ground contact is also grounded to the housing assuring the operator that the coupler is grounded.

With ground check circuits, the coupler ground check circuit is the last to make and first to break. Couplers are designed so that the first contact to make and last to break is the ground contact. All PLM couplers are completely metal enclosed with the outer shell grounded to the ground wires in the cable. Designįrom the beginning, PLM designed couplers to standards subsequently incorporated into mine safety codes in the United States. Published test values backed by a high voltage laboratory and continuous innovations have kept PLM Products, now known as Adalet, as a world leader of cable couplers.

Although cable couplers had been used in the mining industry, it was not until 1957 when requirements began to develop for voltages higher than 5kV and amperages greater than 200 Ampere, that the first 7.5kV 00 AMP coupler was developed by PLM products. PLM products began in 1951 as a supplier of cable accessories for high voltage cables. The Leading Coupler in the Mining Industry History
