雖然光纖具有不導電性的,可以免受衝擊電流,而且光纖中的金屬構件對地絕緣值較高,雷電流不易進入光纖。但由於光纖具有加強芯,特別是直埋光纖具有鎧裝層,因此光纖遭雷擊時,同樣會發生光纜被燒毀或損壞的情況。 如何對光纖做好防雷主要措施? 1)對於直理式光纜線路的防雷,可採取局內接地方式或依照YDJ14-91的規定,在光纖接頭處防潮層、鎧裝層和加強芯作電氣斷開處理,且都不接地,對地呈絕緣狀態。 2)對於架空光纖,架空吊線應電氣連接並每隔2km進行一次接地,接地時可直接或通過合適的浪涌保護裝置接地。 3)光纜進入終端盒後,終端盒應接地,在雷電流進入光纜金屬層內後,終端盒接地可迅速放掉雷電流,起到保護作用。 * * * * * * 創世服務有限公司是一間提供專業數據中心架設公司,擁有一群專業團隊貼心地關注客戶的要求,並提供優質的服務。 想了解更多關於「如何對光纖做好防雷主要措施」的內容,請瀏覽創世官網:http://livservices.com.hk 地址: 香港觀塘鴻圖道37-39號鴻泰工業大廈4樓4室 電話:852-31063235 —————— How to make lightning protection the main measures for the optical
fiber? 1) For the lightning protection of the straight-type optical fiber cable, the
internal moisture resistance layer, the armor layer and the reinforcement core
can be electrically disconnected in the in-office grounding mode or in
accordance with YDJ14-91. Insulated. 2) For overhead optical fibres, the overhead catenary shall be electrically
connected and grounded every 2 km. When grounded, it may be grounded directly or
through suitable surge protective devices. 3) After the optical cable enters the terminal box, the terminal box should
be grounded. After the lightning current enters into the metal layer of the
optical cable, the terminal box grounding can quickly release the lightning
current and play a protective role. * * * * * * LIV is a professional data center to set up a company, with a group of
