|The Physical Object|
A braided bronze armor provides excellent protection against abrasion and other damage. The chlorinated polyethylene insulation resists corrosive chemicals and salt water, and the wires are tin plated for corrosion resistance. This cable also withstands oil and solvents. It’s rated UL for use as marine shipboard cable. Armored cable is a type of flexible metal hose that is used to protect electrical wiring that runs throughout homes in areas where the building codes requires the use of such protective material. Some cities or municipalities require that metal conduit or armored cable be used to protect the wiring in residential and commercial buildings to help prevent fires.
General Cable’s armored cable products offer distinct advantages and deliver maximum performance and ease of installation for a broad range of commercial, industrial and utility applications. The unique characteristics of this all-in-one cable assembly provide an alternative to labor-intensive cable-in-conduit installation methods. Armored cable looks just as it sounds. The coiled metal sheathing that wraps armored cable protects its wires from puncture by nails, unless a nail hits it dead-center. (Even conduit cannot offer absolute protection against a direct hit.) You may want to run armored cable behind moldings where it .

This would minimise the effect of change of resistance with temperature on the current sharing. Test arrangement Each cable sample was about 7 m long. The armour was terminated in brass cable glands with approximately 1 m long tails at each end.

History. Supersedes: Pub Specification for underground armoured cable protected against solvent penetration and corrosive attack (EEMUA, ). Cable ducts: Cable ducting is also a means of offering mechanical and environmental protection to cables, ducts can be plastic, metal or concrete and can be of sufficient size to offer protection to many different cables and electrical circuits.
Other cable accessories are available to offer protection to cables at particular points such as in. Armored cable is an electrical wiring solution where the ground, the neutral, and the Hot wires are encased in a flexible metal sheathing.
It is much more durable and damage resistant than nonmetallic or Romex wire and is approved for use in many more types of construction applications. Armoured cable is covered by a metal sheath which protects the cable from water and extreme temperatures, allowing it to be used in underground or external projects as well as indoor applications.
SWA cable, which means steel wire armoured is heavy and difficult to bend which helps to reduce the risk of pinching and damage.
Except where installed in a conduit or duct which provides equivalent protection against mechanical damage, a cable buried in the ground shall incorporate an earthed armour or metal sheath or both, suitable for use as a protective conductor.
The location of buried cables shall be marked by cable covers or suitable marker tape. The installation of underground electrical systems can be envisaged as the provision of 4 fundamental components: (1) Primary cable.

We make available an excellent assortment of Armoured Power Cables, which is offered at industry leading prices. These cables are mainly used in the underground cabling and connections in control panels of electric control circuits.
Also, we source the raw materials of armored Cables from the authentic and certified vendors of the industry. In HT & LT distribution, 4 core armoured cable is preferred. Inside walls and in other protected locations, less expensive unarmored electrical cable can be installed instead.
Unarmoured cable is mainly used for control systems. Why Should Use Armoured Cable Over Unarmoured Cable. There are a couple of reasons that armoured cable should be used. protection against nail or screw penetration shall be permitted. (2) Notches in Wood, cables or raceways shall be permitted to be laid in notches in wood studs, joists, rafters, or other wood members where the cable or raceway at those points is protected against.
CEC Protection for cable in exposed installations (see Appendix G) Cable used in exposed wiring shall be adequately protected against mechanical damage where it passes through a floor, where it is less than m above a floor, or where it is exposed to mechanical damage.
Armored cable locks offer the lighter weight of a high strength steel cable with the aded protection o a hardened steel sheath that shrugs off attack from bolt and wire cutters. High strength twisted steel cable is permanently forged to an X2P Double Bolt lock head featuring new double rubber coated lock head covers for a comfortable grip and.
For me - mechanical protection? forget it - the existence and common use of the nail gun makes it impractical. Earthed metal - yes, that's the way to go - but there's no provision in for "home made" bits of metal.
Either one of the specified types of armoured or concentric earth cable, conduit to BS EN or trunking to BS EN A wide range of Control Cables (PVC Insulated & Sheathed Flexible Cables) are available with l Cables are very usefull for industrial uasge.
These control cables have high tensile strength and accurate resistance to high temperatures. These cables work in both dry and moist conditions. We offer them in black/gray core colours and gray, black and white sheer colours.
