Armored cables are made of conductors of different materials in metal sleeves with insulating materials and processed into flexible solid components. Armored cables include armored thermocouples, armored thermal resistors, armored heaters and armored leads, which are mainly used for temperature measurement, signal transmission and special heating in chemical industry, metallurgy, machinery manufacturing, power generation and scientific experiments, among which armored thermocouples are the most widely used. The mechanical protective layer of armored cables can be added to cables of any structure to increase the mechanical strength of cables and improve the anti-corrosion ability. This is a kind of cable specially designed for areas that are prone to mechanical damage and corrosion. It can be laid in any way, which is more suitable for direct burial in rock areas.
Armored cables are divided into steel belt armored cables and steel wire armored cables. The main differences are:
Usage: Steel belt armoring is only used for laying directly buried cables or common pipelines, public ground and tunnels. However, thin steel wire armor can withstand general longitudinal tension, so it is suitable for short-distance overhead laying or vertical laying. In foreign countries, there are many steel wire armored cables!
Price: The corresponding steel wire armor is more expensive. Because the production of steel wire armor is difficult and the cost is high.
Ampacity: there is little difference, just choose diamagnetic steel belt or steel wire.
According to the different use environment, choose different armored cables: steel belt armor can withstand mechanical pressure, and steel wire armor can withstand mechanical tension.
