Cable and explosion-proof system

An explosion-proof system comprising:

• a cable comprising:
• electric wires each of which comprising a conductive core and an insulator covering the conductive core;
• an outer cover covering the electric wires, the outer cover extending from a first atmosphere to a second atmosphere less explosive than the first atmosphere;
• and
• a partition supporting an outer surface of the outer cover and separating the first atmosphere from the second atmosphere;
• a first cover comprising a thermosetting resin and covering an exposed portion of the electric wires not covered by the outer cover;
• and
• a second cover covering the first cover and comprising a material higher in fracture strength than the thermosetting resin;
• and
• an explosion-proof machine which comprises the second atmosphere inside the explosion-proof machine and through which the cable is passed via the partition to separate the second atmosphere inside the explosion-proof machine from the first atmosphere.

A cable comprising:

• electric wires each of which comprising a conductive core and an insulator covering the conductive core;
• an outer cover covering the electric wires, the outer cover being supported by a support;
• a thermosetting resin covering an exposed portion of the electric wires not covered by the outer cover;
• and
• a metal covering the thermosetting resin.
