Flexible
Bare flexible copper wire for movable connections
MG is a flexible bare copper wire of flexibility class 5 per GOST 22483. It consists of fine copper wires in tight stranding, which ensures high flexibility. It is used for movable connections: current-carrying jumpers of mobile equipment, welding shunts and flexible contacts in switchgear. Designation breakdown: M – copper, G – flexible.

MG is a flexible bare copper wire of flexibility class 5 per GOST 22483. A large number of fine copper wires in tight stranding provides high flexibility and resistance to repeated bending.
It is used wherever a flexible uninsulated copper connection is required: flexible jumpers between the fixed and moving parts of switchgear, welding machine shunts, flexible current-carrying links and earthing of mobile machinery. The small bending radius (3×Ø) and high flexibility make MG indispensable for demanding installation tasks.
Copper wires
Fine copper wires of flexibility class 5 per GOST 22483. A large number of fine wires (up to hundreds in the larger cross-sections) gives high flexibility.
Tight stranding
With a short lay length to retain flexibility under repeated bending. No insulation.
