Wiring

Telephone Cable Wire

telephone line is a single-user circuit on a telephone communication system. This is the physical wire or other signaling medium connecting the user’s telephone apparatus to the telephone communication network, and usually also implies a single telephone number for billing purposes reserved for that user. Telephone lines are used to deliver landline telephone service and Digital Subscriber Line (DSL) phone cable service to the premises. Telephone overhead lines are connected to the public switched telephone network.

TV Cable Wiring

Cable signals are now a widely utilized method for receiving TV signals. The signals come from a cable outlet mounted in the wall of your home, rather than an antenna. Signals are provided to the cable outlet by your local cable TV company. You can make or change your own in-house cable routing to achieve a variety of service arrangements, including providing signal to multiple TVs. Use this guide to learn how to wire cable TV.

Industrial Building

Smart industrial wiring is based on 3-phase electrical power. 3-phase electric allows less workload to be placed on each wire involved while at once allowing them to work together to give you maximum results. With 3-phase electric, the wires are smaller and the motor is smaller than a typical single-phase motor. These factors allow greater efficiency and longer lasting motors and wires.

There are four types of 3-phase electrical power:

  • Common 3 Wire
  • Common 4 Wire
  • 3 Wire with Grounded Hot Leg
  • Special 4 Wire

Residential building

Red wires and black wires are usually “hot”. This means that there is a current (amps) flowing from the circuit breaker to the electrical box or the appliance in question.

The white wires usually are “returns”. This means that they allow current (amps) to flow back to the circuit breaker after the electricity has passed through the load or appliance in question.

White wires should not be connected together with ground wires, with the exception being back at the circuit panel bus bar. If you fail to observe this rule, then every single time the load is energized (such as turning on an appliance), electricity will flow through the ground wire and the return wire simultaneously. This is very dangerous.

A ground wire is usually bare and attaches to an appliance’s frame. Under normal circumstances, current should not be passing through it. Only when there is a short circuit should electricity pass through the ground wire; this happens so that the circuit breaker will kill the flow of current to the site or appliance.

High Rise Building

Large buildings have a much higher electrical load than small buildings; therefore, the electrical equipment must be larger and more robust. Large building owners will also purchase electricity at high voltages (in the US, 13.8kV) because it comes at a cheaper rate. In this case, the owner will provide and maintain their own step-down transformer, which lowers the voltage to a more usable level (in the US, 480/277 volts). This transformer can be mounted on a pad outside the building or in a transformer room inside the building.

The electricity is then transmitted to switchgear. The role of the switchgear is to distribute electricity safely and efficiently to the various electrical closets throughout the building. The equipment has numerous safety features including circuit breakers, which allow power to be disrupted downstream – this may occur due to a fault or problem, but it can also be done intentionally to allow technicians to work on specific branches of the power system.

About Us

we have carried out various electrical projects, involving all type of internal and external works including supply, errection, testing and commissioning of LT switchgears, cables bus ducting.
