Power cables (YJV) come in armored and unarmored varieties. As the name suggests, armored cables offer significant advantages: high mechanical strength and corrosion resistance. Armored cables are the key elements that make them suitable for diverse environments.
Armored Cable Overview
1) Definition:
This refers to the application of a protective metal layer on the outermost surface of the product to prevent damage to the inner active layer during transportation and installation. Cable armor typically includes an insulating sheath. Cable armor materials include steel tape, steel wire, copper tape, tinned steel wire, and others, and their selection is primarily based on the customer's operating environment and requirements.
2) Function:
In addition to enhancing mechanical protection such as tensile and compressive strength to extend service life, armor provides a certain degree of resistance to external forces and protects against rats, preventing them from penetrating the armor and causing power transmission problems. The armor should have a large bending radius and be grounded to protect the cable. Armored cable mechanical protection can be added to any cable structure to increase its mechanical strength and improve its corrosion resistance. It offers advantages such as enhanced tensile strength and cable protection. Armored cable also offers a certain degree of resistance to external forces, protecting it from rats, which could cause damage to the cable and lead to power transmission issues. The armor should have a large bending radius, and the armor layer can be grounded, thus protecting the cable.
3) Applications of Armored Cable
Armored cable is generally used for fixed-layout power cables. In layman's terms, it is fixed in place and rarely moves, transmitting power.
It is suitable for direct burial, eliminating the need for conduit installation. It is cost-effective and widely used, and is particularly well-suited for direct burial in rocky areas.
Armored cable is suitable for use in areas subject to high pressure, such as highways, roadsides, residential areas, parking lots, and pedestrian streets.
Armored Cable Models
Steel-tape armored cable models include VV22, VVP22, ZRVV22, and NH-VV2.
Steel-tape armored control cable models include KVV22, KVVP2, KVVP22, and ZR-KVV22.
Steel-wire armored power cable models include VV32, YJV32, and ZR-VV32.
Steel-wire armored control cable models include KVV32 and KVVP32.
Armored communication cable models include HYA53, HYAT53, HYA23, HYV22, and HYA22 (rodent-proof, buried).
Armored cables can be easily distinguished by armored and unarmored cables. You can think of armor as armor. For example, if the cable is directly buried without armor, sharp objects can easily pierce the sheath and insulation, potentially causing grounding accidents. This makes it easy to note a very important performance advantage of armored cables.
