How many times are BC Hydro Customers going to pay for failed attempts to save Hydro Transmission Poles?

The  'Bowen Island Study' is really a study on Salt Spring Island

If in doubt on the effectiveness of the boron sticks, use a field bandage .....




And its good to go for another 50 years

However

In real life, not all hydro poles have such ease of access as that which the study used on Bowen Island

But that's okay because it has a Full Bandage Wrap



The Boron Sticks????


When the angle of the dangle ...... is on a 45 degree slope

or

Pulled out of the Ground

The Boron stick is nowhere near the rot which is five to seven feet down

Concrete-replacement-for-wood-BC-Hydo-Poles of the 1970s - 1980s which was a promise to ratepayers that the BC Hydro poles would never ROT

Was true.

But then there's been no mention of the minor detail that the structural galvanized metal inside the concrete poles, would, and did, RUST out.  

Result: Another failed experiment that continues to drive up the cost of electricity today
Spun Beaton Concrete Pole now used as an Ashtray
Therefore Many Ashtrays, or crushed for use on highway projects.

 Kamloops This Week:
“Concrete poles, they’ve been around a long time — since the ‘70s,” BC Hydro community relations manager Dag Sharman told KTW.

“We identified a potential safety issue with the concrete poles and that’s why they’re being replaced.”
Highland Powerlines is the contractor BC Hydro has hired to switch out a number of concrete poles in the Kamloops area, and project manager Rob Oleksyn said the issue has to do with the steel re-enforcement inside the concrete.

“There’s an electrolysis issue they’re having,” he said.

“The concrete is a conductor because it’s got steel inside.

“It’s causing the bolts to fail. It’s actually deteriorating the galvanized bolt inside the concrete pole.”

Oleksyn said a worst-case scenario would likely see a downed line, but Sharman said no issues have been reported and the switch back to wood is a precautionary measure.
