Prior to knowing about the high voltage cable, we need to understand what is high voltage. The amount of voltage power that is above a limit range is called high voltage. The voltage power that surpasses 1000 volts is taken into consideration as high voltage and threatens living beings. High voltage is utilised for electric transmission over long distances, so regarding reducing the loss of existing.
High Voltage Electric wires are used to send electrical power at high voltage. As these cables are totally insulated, they make sure the safety and security of the living being. The high voltage triggers electric shock that may be deadly for them. It contains an internal conductor that stays protected from the outside. The conductor brings high voltage and for that function, more immune wires are required which can birth high voltage.
Parts of High Voltage Cables
High voltage wires primarily contain insulation and conductor. Apart from these, there lots of other components such as a conductor shield, metallic insulation screen, non-metallic insulation screen, inner sheath, laying up, as well as external sheath are likewise present.
Modern High Voltage Cables are less complex, as well as consist of less variety of parts. This consists of conductors, insulation guards, conductor shields, joints, metal guards, and coats. The functions of these elements are as complies with:
- Round aluminium or copper conductors are in charge of bringing short circuit present, as well as having a continuous ton.
- The conductor guard is composed of semiconductor material. It reduces the possibility of electrical existing discharge at the interface of insulation and conductor.
- All the insulation parts contain polymers that supply defence to the conductor. It ensures far better transmission of high voltage with minimum loss.
- The cord coats are comprised of polymeric substances that protect against moisture, as well as conserve the wire from getting deteriorated. It also decreases chemical intrusion that boosts the lifespan of wires.
Types of wires
A cable is utilised to transmit electric power. They securely supply electrical power from the source of power to various tons. Various cable is made accordingly to attain this objective.
- Rubber wires are comprised of oil products or rubber gotten from tropical trees. They are liable to damage as it absorbs wetness.
- Rubber cables are changed to develop vulcanized rubber wire. In this sort of cord, rubber is blended with mineral substances like lead, zinc, or sulphur. Vulcanised rubber cables are more long-lasting are having higher mechanical strength contrasted to rubber cables.
- Polyvinyl chloride cable has great dielectric strength. It is tough and durable as polyvinyl chloride is utilised for insulation.
