16mm² Double Core Armoured Power Cable

Low voltage cable structure
It consists of three parts: core, insulating layer and protective layer. The wire core is used to conduct current, and is generally formed by twisting multiple strands of copper wire or multiple strands of aluminum wire. There are several types of low-voltage cables, such as single-core, double-core, three-core, and four-core. Two-core cables are used for single-phase lines, three-core and four-core cables are used for three-phase three-wire lines and three-phase four-wire lines respectively, and single-core cables can be used for single-phase or three-phase lines as required. Commonly used low-voltage cables have core cross-sectional areas of 10, 16, 25, 35, 50, 70, 95, 120, 150, 185, 240 mm, etc.

The protective layer
One or more layers of metallic or non-metallic material covering the cable. The protective layer is used to protect the insulating layer from external damage and moisture intrusion during transportation, laying and use.
(1) Paper insulated cable protective layer. The protective layer of the paper insulated cable is divided into two parts, the inner sheath and the outer sheath. The inner sheath is directly extruded on the insulating layer, which not only protects the insulation from moisture, but also prevents the insulating oil from flowing out, and has a certain mechanical strength. There are three types of inner sheath: lead cladding, aluminum cladding and polyvinyl chloride cladding. The outer sheath protects the inner sheath to increase the ability of the cable to withstand external mechanical forces and resist corrosion. The outer sheath includes an inner liner layer, a metal armor layer and an outer layer. The inner lining layer protects the metal sheath from being damaged by the metal armor layer, and anti-corrosion measures can be added; the metal armor layer can withstand mechanical external force; the outer layer can protect the armor metal from external corrosion.
(2) Plastic cable protection layer. Usually a polyvinyl chloride sheath is used over the plastic insulation.
(3) The protective layer of the rubber cable. The protective layer of the rubber cable is divided into an inner sheath and an outer sheath. There are three types of inner sheath: PVC sheath, neoprene rubber sheath (non-combustible rubber) and lead sheath; the outer sheath is divided into three types: steel tape armor, rubber sheath and plastic sheath.

VLV22 is VV copper core cable replaced by aluminum core cable, double steel tape wrapped armored power cable; the following electric encyclopedia will introduce what kind of cable vlv22 is, the picture and model specification of vlv22 cable, and the ampacity meter of vlv22 cable.

Full name of VLV22 cable: aluminum core conductor PVC insulated PVC inner sheath double steel tape wrapped armored PVC outer sheath power cable. VLV22 cable code meaning:
The first V: cable insulation material PVC
First L: Aluminum
The second V: cable inner sheath sheath material PVC
The first 2 means galvanized steel tape armor
The second 2 indicates that the outer sheath of the cable is PVC sheath material

The difference between VLV22 and YJLV22 cables
YJLV22 is cross-linked insulated, PVC sheathed aluminum core armored cable.
VLV22 is PVC insulated, PVC sheathed aluminum core armored cable.
The current carrying capacity of the two cables is different. The temperature of the core of the YJV cable can reach 90 degrees, while the temperature of the core of the VV cable is generally only 65 degrees.
YJLV22 is more expensive than VLV22 cables.
