Application
Portable dual rated 5000/15000 volt jumper
cables can be used as temporary jumper
leads for portable or mobile substations,
or for temporarily by-passing damaged or
faulted sections of power cable. The finely
stranded conductor provides an exceptionally
flexible cable that can be easily trained
and connected in confined areas such as
transformer vaults and switch gear
enclosures.

37-221
Red Jumper Cable
Flexible • 5000/15000 Volts • 90°C

Features
n Extremely flexible stranding
n Bright red thermosetting jacket
n The conductor shield is bonded
   to the insulation – providing easy,
   clean stripping
n The 90°C insulation has excellent
   dielectric properties and is highly
   resistant to heat, moisture
   and ozone.

Ratings & Approvals
n ASTM B-33: Standard Specification for Tinned Soft or
  Annealed Copper Wire for Electrical Purposes
n ASTM D2802: Standard Specification for Ozone-
   Resistant Ethylene-Alkene Polymer Insulation for Wire
   and Cable

Application Note
Jumper cables should NOT be used in place of normal high voltage cables. They should
be isolated in areas where contact with people is limited. Because jumper cables cannot be
protected against prolonged contact with other conductors or grounds by shielding, these
cables must be positioned away from contact with grounds, transformer cases, cross-arms,
etc., to avoid possible high stress and capacitance leakage. Cables should be installed with at
least one cable diameter of separation between adjacent conductors and between conductors
and all metallic and/or electrically grounded parts. These cables are not intended for
permanent service.
