Model, Name& Application

Model		Name	Application
CU Core	Al Core
VV	VLV	CU or Al Core PVC Insulated PVC Sheathed Power Cable	Suitable for indoor and outdoor laying. It can bear certain laying pulling but can't bear mechanical force. Single core cable can't be laied in magnetic pipes.
VV22	VLV22	CU or Al Core PVC Insulated Steel Tape Armoured PVC Sheathed Power Cable CU or Al Core PVC Insulated Thin Steel Wire Armoured PVC Sheathed Power Cable	Suitable for direct buried.It can bear mechanical force but can't bear high pulling force
VV32 VV42	VLV32 VLV42	CU or Al Core PVC Insulated Thick Steel Wire Armoured PVC Sheathed Power Cable	Suitable for high fall area.It can bear mechanical force and certain pulling force

Note:Single Steel Tape Armoured Cable Used for Direct Current Supply System Only. If for Alternating Current Circuit, Aluminum Wire Armoured is Avaiable.
