High-voltage wires are the most popular type of cable products. The material is indispensable in cases where it is necessary to transfer electricity of increased power at a voltage of more than 35 kV. Most often, a high-voltage wire is used to transmit an electric current pulse to spark plugs from coils.
Quality products should have the following characteristics. Firstly, the transmission of the pulse should occur with minimal loss of electricity. Wires should maintain their characteristics and properties in the temperature regime from minus 30 to plus 100 degrees Celsius. And also withstand voltage up to 40 kV.
In their design, high-voltage wires consist of insulation (protective layer), caps, metal contacts and conductive conductors. The last element can be made of stranded copper, of thin metal wire with dielectric upholstery. In addition, the core may be non-metallic, with distribution high voltage.
For insulation use a single-layer or multi-layer coating of a dielectric material (plastic, silicone, rubber). The protective layer carries the following functional load. It prevents the leakage of electric current, protects the cores from the harmful effects of combustible lubricants, high temperatures, moisture, harmful fumes, as well as mechanical damage.
Contacts or metal lugs provide electrical connection of the cores with the distributor cover, contact candles or ignition coils. Caps are used to protect the connections from aggressive environmental influences, and also prevent electric leakage.
High-voltage wires are divided into several groups. Mounting provides inter-unit and internal connections of devices and electronic equipment. Ignition wires are widely used in various fields. They participate in the ignition circuit of jet engines, internal combustion engines, and powerful lighting equipment. These materials are operated at high temperatures, voltages and impulses. They are used in road transport, to which there are requirements for noise suppression.
Impulse wires transmit electric current in electronic and electrophysical devices. They allow you to distribute a limited number of powerful oscillatory and periodic pulses. Flexible high-voltage wires are also widespread. They are used in movable current collectors to transfer the potential of low power.
Cable materials are produced by many well-known companies. Tesla high voltage wires enjoy a good reputation. These high-quality materials are used in various fields. Ignition wires of the Czech concern "Tesla" form the basis of the entire automotive range. They are used to transfer current from the distributor to the spark plugs of the car.
