Aluminium Sheathed Cables

These power cables are used for exposed and concealed wiring, in wet and dry locations, and where exposed to the weather. They may be installed in ventilated, unventilated and ladder-type cable-troughs, and ventilated flexible cableways.

Aluminum-Sheathed Power Cables may be single-, two-, three- or four-conductor, the conductor(s) being annealed, bare, compressed-round stranded copper. The insulated core is enclosed in a liquid- and vapour-tight solid corrugated aluminum sheath, covered by a PVC jacket.

Concentric Neutral Cables

These power cables may be used in dry or wet locations, for a wide variety of types of installations, and may be single- or three-conductor. The two standard constructions are Unjacketed and Jacketed, the latter being most frequently used.

The conductor is typically annealed, bare, stranded copper, but tin-coated wire and solid conductors are also available.

The concentric neutral conductor, from which the cable derives its name, is bare or tin-coated copper wire, applied helically over the insulation shield. These wires act as the metallic component of the shield and the neutral, at the same time.

Shielded Cables

Shielded Power Cable may be single-or three-conductor. The basic construction begins with a conductor of annealed, bare, solid or concentric-stranded copper, which may be compact or compressed. This is followed by a semi-conducting conductor shield, insulation, and then a semi-conducting insulation shield.

Metallic shielding follows, which is usually either gapped or lapped copper tape. Other types of metallic shielding are available, including concentric wires and longitudinally corrugated copper tape. The outer jacket is either PVC or PE.

Submarine Cables

For submarine installations, usually Self-Contained Liquid-Filled Cables (SCLF), or Solid Dielectric Cables are selected, depending on voltage and power load. SCLF Cables are capable of handling very high voltages. However, for medium-voltage installations, a Solid Dielectric Cable can easily fulfil the electrical demands of the system.

A submarine Solid Dielectric Cable is shown in the illustration. Its construction begins with a compact stranded, annealed, bare copper conductor, followed by a semi-conducting conductor shield. A copper tape shield is helically applied, followed by a lead-alloy sheath. Due to the severe environmental demands placed on submarine cables, a lead-alloy sheath is often specified because of its compressibility, flexibility and resistance to moisture and corrosion. The sheath is usually covered by a number of outer layers, comprising a PE or PVC jacket and metal wire armouring.

Mining Cables

A number of different types of cables are used in mines. There are fixed mining cables and portable mining cables, the latter being described here. The key requirements of portable cables are flexibility, and resistance to mechanical abrasion and damage. Due to the additional demands put on portable mining cables used for reeling and dereeling applications, special design may be required.

There are many types of portable mining cables. They are available in ratings up to 25 kV, and may have as many as five conductors.

An example of SHD-GC Cable, is shown in the illustration. It has three insulated, shielded conductors, two bare ground wires, a ground check wire, and an overall jacket. The conductors for this cable are annealed, bare or tinned copper wires.

The braided shield may be tin-coated wires, or a tin-coated copper wire/textile composite. The grounding conductor(s) annealed, bare or tinned, stranded copper wires, and the ground check conductor is annealed, bare, stranded copper wires with EPR insulation and nylon braid, elastomeric jacket holds the conductor assembly firmly in place, to minimize snaking and cork-screwing during reeling and dereeling.

Paper-Insulated Lead-Covered Cables (PILC)

PILC cables are used in power distribution and industrial applications, and they may be installed exposed, in underground ducts or directly buried. Their design begins with annealed, bare copper conductor(s) which may be round, concentric, compressed or compact stranded, compact sector, and in larger sizes … Type M segmental stranded. An example of compact sector conductors is shown in the illustration. The insulated cable core is impregnated with a medium viscosity polybutene-based compound. The combination of the excellent electrical and mechanical characteristics of the liquid and the paper has resulted in a reliable and economic insulation, which now claims a history of almost 100 years. It is little wonder why so many utilities and power-consuming industries, still continue to specify PILC.

To prevent the ingress of moisture, a seamless lead-alloy sheath is applied. The outer jacket may be PVC or PE, and if required by the application, armour is available.

Teck Cables

Teck Cables were originally developed for use in mines, but they are now widely used in primary and secondary industries, chemical plants, refineries and general factory environments. They are also used in multi-storey and commercial buildings. They are flexible, resistant to mechanical abuse, corrosion resistant, compact and reliable. A modified Teck Cable construction may be used for vertical installations, such as in mine shafts and multi-storey buildings, where the armour is locked-in-place to prevent slippage of the inner core.

There are many different combinations of conductor size, voltage rating, armour type and so forth, available in Teck Cables to meet the requirements of particular installations.

Annealed, bare, copper is used for the conductor (s), and they are usually compact stranded to reduce diameter. In multi-conductor cables, the insulated conductors are cabled together, including the bare copper bonding (grounding) conductor. In shielded multi-conductor cables, the bonding (grounding) conductor is positioned to contact the copper shields. A PVC outer jacket which may be colour-coded depending on the rating of the cable is applied.
