The shelf life of mechanical cables is generally 30 years.
The national warranty period for wires and cables is 30 years, but the specific warranty period should be determined according to the type, use requirements, temperature and applicable methods of the wires and cables. Under normal circumstances, the cable shelf life is about 15 years, but this only applies to normal use environments, such as when the rated temperature is below 70 degrees. If used in a working environment above 70 degrees, its service life may be greatly shortened. Therefore, correct use and maintenance in accordance with the instructions for use are the key to ensuring the service life of the cable.
In addition, the warranty period of wires and cables refers to the quality assurance period provided by the manufacturer for the wire and cable products it produces. During the warranty period, if the product quality problem causes difficulties or failures in use, the manufacturer needs to bear responsibility and be responsible for repairing or replacing the product. Under normal circumstances, the warranty period of wires and cables is one year, but for some specific application scenarios, such as underground cables, the warranty period may be extended by 3.
National standard wires and cables generally do not have a shelf life, but there is a cable service life, which depends on the materials used and generally does not exceed 20 years4. Therefore, for mechanical cables, although the national warranty period is 30 years, in actual applications, its service life may be affected by many factors, including the use environment, maintenance conditions, etc.
