What is the tension rating?

The voltage evaluation is an evaluation based on research and experiments that help determine how much voltage can be safely used by a specific device or by wiring throughout the lifetime of the device or wiring. For electrical and electronic devices, this evaluation is determined during the development and testing of the product by increasing the voltage level until the device is disintegrated or non -functional. The voltage evaluation is not the maximum at which the break -up is, the maximum percentage of the maximum and is determined as a safe level for prolonged use. To connect the voltage, it takes into account the materials used for the connection of the connection, the wire thickness and the intended use of the wiring. For all forms of electrical conductors, the voltage evaluation scale was determined.

Purpose

The main purpose of the voltage evaluation is to ensure that the user of wiring or device can reasonably expect the material to use for the intended purposes and do not fit with the hazard or damage to the device. From this point of viewThe evaluation will specify how much electric current can be safely transmitted by cabling and defines the type of current that can be safely performed by wire. After the standard set by appointment, the voltage significantly reduces the chances of overheating and electrical fires.

ranges

There is no commercially produced device that has not been tested and certified with voltage evaluation. Depending on the design and the intended use of the device, the evaluation could vary greatly. For example, the voltage evaluation for the copper cable of insulated mineral (Mi) is usually almost 1,000 volts. Cabbage for table lamps and other small households is usually much lower.

Safety Standards

by setting the evaluation that determines the highest voltage that cabling can carry and still operate opera under acceptable security limits, government and other organizations can set standards for involvement in dependentosti on his applications. The connection used in the electrical system of the residential house, for example, must usually meet specific standards and be to a certain extent. The same applies to involvement in public buildings. Many types of machines used in the production of goods and services must also include a connection that meets the standards and has a voltage evaluation that is considered to be reasonable to the current level that the machine will have to work in the long term.
