Hot Supercote is a type of coated high tensile wire that can be electrified.
The three black lines that radiate from the steel wire in the center
conduct electricity because of their high carbon content. This kind
of wire matches regular Supercote in general appearance (highly visible
and attractive) and in safety for horses due to its large diameter.

Like regular Supercote, Hot Supercote can be installed using the same
methods as MAX-FLEX high tensile smooth wire. It can be
used in combination with smooth wire or other fence wires. Best of all,
it will fit into some standard high tensile wire insulators (like the
MAX-FLEX Black or White WOR for line posts and the S insulator
for corner posts) or can be installed with special tubing made to fit
Hot Supercote. Tubes cost less but must be slid along the wire from
an end to every post and they provide less clearance from the post than
WORs.
