Spiderman in Tainan? No, just Taipower engineers at work

Spiderman in Tainan? No, just Taipower engineers at work

2022-11-03

The internet is wondering if Spiderman might have moved to Tainan. A video posted online showed people moving along power cables above a highway. Many people were mystified by the unusual sight. But the truth is simpler – it’s Taipower engineers at work. As the engineers explain, getting up on the cables is just another part of keeping the power grid in order.

This video was posted online. A driver is cruising the highway when suddenly they spot a number of dots on the electricity cables overhead. From far off, they look like birds. But closer up, you can see they’re people. In awe, the driver wonders if Spiderman is at work.

These are the cars that can move along electric cables. They have to be operated by human power. The engineers pull themselves along as they work, like cyclists in the air.

You need specialist skills to get up there. It must be really hard work!

Separators between the electric cables prevent them from swinging in the wind and touching other cables. That ensures the safety of our power supply.

As this engineer explains, the wind can swing electric cables too close together. That creates a risk of short circuits. So separators must be fitted between the cables. The cars comprise a box to seat an engineer and wheels that fit onto the cables. The engineer pulls on the cables to move themselves along, all the while installing, repairing or even dismantling the separators between cables. It’s vital work to maintain the power grid.

When engineers go up, we have a brake here. It brakes automatically at a certain distance. They stop there and install a separator between the cables.

The video posted online shows separators being dismantled and replaced on a bifurcating cable. These aerial maintenance tasks may be routine, but they don’t take place every day. No wonder it made viewers think of superheroes.

國道半空驚現「蜘蛛人」台電員工搭「宙乘車」維護高空線路

2022-11-03

台南有民眾日前開車上高速公路,在半空中看見似乎有高空電纜車滑行,簡直像蜘蛛人掛在半空中特技表演,畫面被PO上網,也引起許多網友討論。原來這是台電人員搭乘著「宙乘車」,在高空維護高壓電線路,也讓人看見,台電人員不為人知的辛苦一面。

就是這段影片被PO上網,民眾行車在高速公路,赫然發現半空中的電線上,怎麼會有一個個的流籠,遠遠望見還以為是有鳥兒站立,接近時赫然發現,竟然還有人在高空滑行,眼看著蜘蛛人在博命演出,不得不感到敬佩。

這種高空小車,叫做「宙乘車」,掛在電纜上滑動,必須用人力滑行,邊工作邊拉,好像人力自行車。

“要有專門技術才能夠上去,這一定是非常辛苦”

“導線間隔器的部分,防止風吹擺動不會去碰觸到相互的導線之間,確保我們供電的安全”

原來鐵塔間的導線,會因為風速過高而碰撞,產生斷線的危機,因此必須在導線間安裝間隔器。至於宙乘車是由輪子和乘坐箱體組成,把輪子架在導線上,由高空專業人員,雙手拉著導線行進,以便安裝、拆除或修復間隔器,對輸電線路是很重要的作業。

“人員上去之後,這裡有個煞車器,距離到了它會直接煞車,停在那個點,裝設導線的間隔器”

網友所PO的影片內容,是在執行分歧線導線的更換,拆裝間隔器。這樣的高空作業,例行檢修電線更換,才會看得到,並不是很常見,民眾會意外發現,也是種難得的經驗,更能體會台電維修人員,罕為人知的辛勞。
