No HV lines in my part of CA are insulated...the lower voltage lines from the x-former to your house are the only ones that are insulated (except for the neutral/ground line).
******(Regardless of the installation method, the point of demarcation is the connection of the insulator
string)******to the overhead conductor at the dead end structure. The dead end referenced should be
the structure that transitions the line to any type of substation equipment.
Got it
To date, almost no articles on the lahaina fire mention the windmills along with the wind power batteries that are about 10 miles SW of lahaina. This was built in two stages (2006 and 2012). it is very apparent to visitors who fly in and out of the airport and who pass it along highway 30 between the airport and west maui (lahaina, etc). from the planning perspective, it is or at least was a source of pride by the government which is trying to go carbon neutral in a few years by getting rid of its oil fired plant. the wood poles are probably ok if they are periodically replaced but a better solution would be reinforced concrete poles (manila, guam, taipei, tokyo, etc) or undergrounding (honolulu, etc).
There is also the new Kuihelani Solar Farm in central maui, currently scheduled for completion in 2024. It also has a (expensive?) battery backup.
all of this is or should have been well known at the maui county and state government level. suing hawaii electric foe negligence seems to be a transparent charade imho if maui and state government directed hawaii electric (a privately owned but supposedly regulated utility). the real question might be who was asleep at the regulatory wheel for Hawaii Electric, and allowed funds to be allocated for politically correct windmills and solar farms when the infrastructure was allegedly starved for maintenance funds? why are the windmills and solar farm financially independent from Hawaii Electric and therefore legally shielded from their fair share of liability for the lahaina fire? for shunting funds away from the lahaina power grid?
a blue sky solution might involve declaring lahaina a cultural heritage site for the purposes of allowing more state and federal funds to be allocated towards it. lahaina is or at least was the historical jewel of native hawaiian culture. restoration in some sense is essential to hawaiian culture. county and state government destroyed lahaina so county and state government should at least provide leadership and vision needed to meet the challenge to restore and protect lahaina (and its citizens).
note:
hawaii telcom ownership (just in case it pops up later):
owned by: hawaii telcom holdco
owned by: macquarie infrastructure and real assets (australia)
owned by: macquarie infrastructure partners (australia)
owned by: macquarie group limited (australia)
owned by: hill samuel & company (uk)
owned by: Lloyds Banking Group’s Offshore Private Banking (uk)
Ok. What could have caused that intense level of heat?
Several things actually can cause that level of heat, but only one fits here: pump a lot of electricity into the fire preferably through metal. That is how foundaries usually melt aluminum and hardened steel. Since they did not shut off the power, it fits.
Congratulations. I'm a customer that pays your salary and you didn't answer the question as to how you came up with the 10-20 times cost to the user since I am a user of electricity that is delivered to my home via underground cables/wires/conduits and my end user price is the same as any other user in my town that gets their electricity delivered via overhead wires.
I don't give a fat rat's ass about the costs for repair of an underground wire vs overhead wire, Mr. Engynnneer.
The utility company has factored the costs into their sale price, and have decided that they can deliver my underground electricity at a reasonable cost {or otherwise, there would be wires hanging all over my neighborhood, and there are none}.
I would not want to pay 10-20 more for underground delivered electricity, and no rational electrical distribution engineer would posit that as a reasonable premise in an argument, Mr. eegator.
With that kind of logic, stay in the engineering trade, because you can't stand up in a rational discussion.
Your service wire, cable triplex, is secondary voltage in a URD. It isn’t transmission.
The poles near your neighborhood, aren’t transmission, they’re distribution voltage.
F’ing retard.
You don’t pay 10-20 times the cost because it isn’t underground transmission yet. That’s what would happen if it was.
Got it. Thanks.
About a year ago some poles in my neighborhood, just outside of town but leading to new subdivisions, went down one after another with an unusual wind burst. About 10 of them just snapped in two. They were probably from the 60's, but the real problem was with the expanding size of the town they had been loaded up with too many cables as the town grew. Too much weight; the high winds were just happy to throw it around, though.
Any lineman could have foreseen the breakdown, but since it was ignored they all got to work double time making the repairs.
