Suojajohtimen

Suojajohtimen is a type of electrical conductor used to protect cables from mechanical damage and electrical surges. The term "suojajohtimen" is Finnish, meaning "protective conductor".

Suojajohtimen is typically installed in conjunction with building wiring and grounding systems. Its primary function is to provide a safe path for electrical currents to flow in the event of a fault or electrical surge. This helps to prevent damage to equipment and appliances, as well as reduce the risk of electrical shock or fire.

Suojajohtimen is usually made of copper or aluminum and has a cross-sectional area that is larger than the conducting cable it is designed to protect. This allows it to carry the electrical current safely and efficiently. The conductor is often insulated with a durable material to protect it from corrosion and mechanical damage.

In electrical installations, suojajohtimen can be connected to the neutral conductor of the wiring system, or to a grounding point such as the earth electrode. It can also be connected to a surge arrester or varistor to provide additional protection against electrical surges.

Suojajohtimen is an essential component of modern electrical installations, providing an additional layer of protection for buildings and their occupants. Its installation and maintenance are typically governed by local electrical codes and regulations, and are usually performed by licensed electricians.

The use of suojajohtimen can help to prevent electrical accidents, reduce the risk of equipment damage, and ensure a safe and reliable electrical supply.
