MIND cable means Mass Impregnated Non-Draining type cable. In paper insulated cable the impregnating oil compound has a tendency to drain or migrate when laid on step slopes. Such migration of impregnating compound makes the paper insulation dry at the upper portion which creates voids and initiates ionization. Moreover accumulated compound at the lower portion creates pressure on the metal sheath and may cause its damage. To overcome this difficulty, the paper insulated cables are impregnated with a non-draining resin base compound containing petroleum jelly or microcrystalline waxes. These MIND cables are available for all voltages up to and including 33 kV. These cables are suitable for vertical run particularly on hills or in mines.
