Description:
An 8 core alarm cable is used for a wide range of applications including security systems, power-limited controls, fire-alarm systems, single line telephones and smoke alarm systems.
An 8 Core Alarm Cable is one of the most common and high-quality corded telephones on the market. This cable can be used for a variety of applications. The cables are designed for convenience and are available in a variety of colors and materials. Customers can order these corded telephones from any store. They can also be ordered online. Depending on the type of cable that you need, you can order up to a dozen.
Alarm cable is used for the installation of alarm systems across both domestic and commercial properties, containing bundles of wires which are sheathed to protect against any interference in frequency.
These cables are used in high rise buildings, commercial complexes, schools, educational institutions and hospitals, etc. These cables are used where fire safety is utmost important.
An 8 Core Alarm Cable is used for a wide range of applications, including security systems, sound and intercom systems, power-limited controls, fire alarm systems, single-line systems, carbon monoxide alarm systems and more.
Construction of Power Cable
There are various parts of cable to be taken care of during construction.The power cable consists of Conductor, insulation, lay of multicore cables, beading, armoring and outer sheath.
Conductor
Conductors are the power carrying path in the power cable. Conductors are of different materials. In the cable industry, we use aluminum and power cables for conductors.
Insulation
After the conductor, the next part in the construction of the power cable comes the insulation. The insulation provided on each conductor of a cable by PVC and Rubber. The insulating material is based on operating temperature.
Beading
This portion of the 8 core alarm cable is known as the inner sheath. It is used in multi core cables. It works as a binder for insulated conductors together in multi core power cables and provides beading to armor.
Outer Sheath
This is the outermost cover of the cable normally made of PVC, and Rubber.
Types of Cores and Electric Cables at your home
While roaming around your home, you’ll find a variety of homes and its appliance, and each cable has a voltage limit. Each cable carries an electrical current around your home and its appliances, and each cable voltage has a limit. Within each cable are ‘cores’ which are made of copper wires that are coated with insulated plastic and are color coded for its purpose. These cores are then wrapped within the cable by another layer of tough, insulated plastic.
3 Core Cables
3 Core Cables are used in domestic light fittings that are two way light switches.The cable is made of 3 solid cores, which are insulated and wrapped in an outer PVC sleeve. The colors of these cores are brown, black, gray, with a bare earth core.
SWA Cables
Steel Wire Armored cable is used to move power underneath the ground by burying the cable, or overhead using a catenary wire.
SWA has two to four core cables. The cable is formed up of these inner cores, which are individually sleeved, then wrapped together with a layer of plastic covering. Then it is protected with a layer of wire armor, before finishing with a final outer layer.
Flex Cables
Most of your portable electronic appliances and light pendants will use flex cables, as it allows for flexible connections to the power point. The cable is formed in a cross section with 2 cores inside a PVC outer sleeve coating.
Conclusion
In this article, we discussed the construction of power cables, types of cables and construction of 8 core alarm cables.
