It is also common to find armoured cables in places where rodents are present, as well as in installations in premises with a risk of fire and explosion ATEX. The use of extra flexible rubber cables is very varied. We can find rubber cables in fixed industrial installations as well as in mobile service.
Welding cables should have a rubber sheath, which allows high currents to be transmitted between the welding generator and the electrode. High Security Halogen Free LSZH Cables with low smoke and corrosive gas emission in case of fire are suitable for use in wiring of electrical panels and public places , installations of all kinds in public places, individual derivations, emergency circuits, public distribution networks and also for mobile service.
These cables are specially designed to transmit electrical energy in the extreme conditions that occur during a prolonged fire, guaranteeing supply to emergency equipment such as signalling, smoke extractors, acoustic alarms, water pumps, etc.
Their use is recommended in emergency circuits in places with public concurrence. Control cables for fixed or mobile installations should be extremely flexible, as they are mainly designed for small household appliances, for the interconnection of machine parts used for manufacturing, for signalling and control systems, for the connection of motors or frequency converters, for signal transmission where the voltage induced by an external electromagnetic field may affect the transmitted signal or for power supply connections to avoid generating electromagnetic fields.
These are flexible and shielded cables for the transmission of signals between equipment in industrial installations. Especially suitable for optimum data transmission in environments with a high level of electromagnetic interference. These cables are particularly suitable for connecting photovoltaic panels , and from the panels to the DC to AC inverter. Thanks to the design of their materials and their cover, which is especially resistant to solar radiation and extreme temperatures, they can be installed outdoors with full guarantees.
There is a wide variety of electric cables for special installations such as: temporary light garland installations at trade fairs; connections for overhead cranes, hoists and lifts; applications in submerged pumps and drinking water areas such as aquariums, purification systems, drinking water fountains or in swimming pools for lighting, purification and cleaning systems. They are cables perfectly adapted for the transportation and distribution of energy in Medium Voltage networks.
For transportation and distribution of energy in Medium Voltage networks. Copper and aluminium medium voltage cable for special applications. Especially recommended for installations where there is a risk of presence of oils and chemical agents of the hydrocarbon type or their derivatives. An electric cable consists of:. The insulation consists of placing an insulating coating on the conductor to prevent current leakage.
They are classified into two large groups: thermoplastic and thermoset. Each cable has a standard designation. This designation is composed of a set of letters and numbers, each with a specific meaning. As the name suggests, this type of cabling is formed from two cores, insulated with PVC outer sleeve, and an earth core between the two. The harmonised colours for this cabling is made up of brown sleeving for the live core and a blue sleeving for the neutral core.
The earth core will be clear to see in green and yellow sleeving but comes bare when you install, you then must cover with insulation sleeve. You will find twin core and earth cabling used all over your home in a variety of sizes. Domestic light fittings that are controlled by two switches two way lighting use 3 core and earth for connections between the two switches.
The cable is made up of 3 solid cores, which are individually insulated and wrapped in an outer PVC sleeving. The colours of these cores are brown, black and grey, with a bare earth core to be insulated with green and yellow sleeving. For outside use, Steel Wired Armoured SWA cable is used to move power underneath the ground by burying the cable, or overhead using a catenary wire. The number of cores within the cable can range from two to four, depending on the purpose.
The cable is formed up of these inner cores, which are each individually sleeved, then wrapped up together with a layer of plastic sleeving, which is then covered with a layer of protected wire armour, before finishing with a final outer layer.
One million circular mils is the area of a circle with mil 1 inch diameter. An older abbreviation for one thousand circular mils is MCM. Stranded wire AWG sizes.
AWG gauges are also used to describe stranded wire. In this case, it describes a wire which is equal in cross-sectional area to the total of all the cross-sectional areas of the individual strands; the gaps between strands are not counted. Stranded wires are specified with three numbers, the overall AWG size, the number of strands, and the AWG size of a strand.
The number of strands and the AWG of a strand are separated by a slash. Mon - Fri 8am - 5pm Closed Sat - Sun. Electrical Cable Types.
