in power exports

WINNIPEG (CP) — In-
_ creased exports of electrical
power from Manitcba to the
United States could make the
province a leader In
designing improved high- .

systems.

The physical plant of
Manitoba Hydro, ‘with its
hundreds -of kilometres of

. high-voltage ‘ines, provides

the. “practical, large scale

“laboratory” essential for.

such research, says Rdmund

Kuffel, dean ‘of engineering

at, the ‘University of Mani-'
.

Kuffel adds that the ex-
pertise of Manitoba Hydro
staff also gives-the province

would include finding better
transmission systems and

insulation materials ana
studying the possibility of
underground long-distance
lines. . ;

Abel Katahcire, one of
Kuffel’s student assistants,

“T's (air) pollution, which

“When. insulation gets
contaminated, you ‘have
flash-over: (reducing the

The search for better
materiafs' focuses on
minimizing such problems,
while reducing insulation

costs. .

Manitoba now has two 230-

stations to North Dakota and

‘And Manitoba Hydro is
optimistic about even higher
voltages being maved gouth
in the next decade, says
system operations director
Will Tishinski.
With its current
generating capaelty,
Manitoba Hydro waa able to
sell $25-million -worth of
surplus electricity in the first
four months of 1979, about 60
per cent of it to the U.S.
Tishinski says the U.S.
purchases .are 15-to 20-per-

cent higher than for the
same period last year.

Kuffel, a member of the
Manitoba Hydro board of
directors, says the federal
government would pay half
the costs for setting up the
centre with the other half
coming from the utility's
operating budget.
