((alert, we can't find this right now, when we do we will drop the price back to 175.99))This Brand New 60 foot long Power Traveling Cable has Tin-plated copper wire of 0.128" diameter wire making it 8 AWG or Gauge .General and Heavy Duty Indoor outdoor Flexable Electrical wiring .Normal price for this Brand of Cable is $4.30 per/ft making this worth $258 ,but It's for sale for 2/3 price at $171.99 .This would work great for wiring Hanging and moving trolleys and hoists , Machinery Agricultural Industrial Welder Oven Heater anything up to 600 volts (even a nice 60' extension cord for a welder ).This product is manufactured in Japanese standards Brand Name: Sumitomo 2PNCT 5.5mm .The outside diameter of the cable itself is .600" or almost 5/8" O.D.
Here: some specs. from a few places

 SUMITOMO ELECTRIC WIRE INDUSTRIES
These cables are designed to japan electrical appliance and material safety law.
In insulation,ethylene propylene rubber is used and in jacket,polychloroprene rubber is employed.
2PNCT is superior to 1CT,2CT in the followings.
①Ampacity is bigger
②Nominal overall diameter and mass are smaller.
③Better oil resistance and abrasion resistance.

[Features]
• Class two EP rubber insulation polychloroprene rubber cabtire cable.
• The insulation consists of ethylene propylene rubber while the sheathing is made using polychloroprene rubber, providing excellent heat resistance and flexability.
• Features a larger allowable current than the general CT, with smaller sizes usable depending on the size.

For wiring of power circuit of mobile electrical equipment below 600V or below AC 750V or control circuit of each equipment.
Excellent operating performance due to easy flexibility and core identification.
