高壓穿牆套管，Indoor-Outdoor Antifouling Type wall bushing
概述summarize
電站用穿牆套管適用於35kV及以下電壓等級的電站、變電所配電裝置及電器設備中，供導線（母線）穿過接地隔板，牆壁及封閉配電機構中作為絕緣支持和外部導線（母線）連接用。
High pressure wall bushing of power station is suitable for up to and including 35 kv voltage grade of power plant, substation, power distribution equipment and electrical equipment, For lead (bus) through the ground plate, Walls and closed distribution agencies as support and external insulation wire (bus) in connection with.
高壓穿牆套管分類Product categories
電站用高壓穿牆套管分為戶內和戶外兩大類，有銅導體、鋁導體及不帶導體的母線式穿牆套管三種結構，並有普通型和耐污型兩大類產品。
Wall bushing divided into two big series: indoor and outdoor，Three kinds of structure with copper conductor and aluminum conductor and busbar wall bushing without a conductor，And have a regular and fouling resistance type two categories of products.
由於產品較多，為便於用戶查詢，將產品分別分類介紹。其中又將耐污型系列分為爬電比距2.0cm/kV以下和2.5cm/kV以上兩類。特別推薦爬電比距2.5cm/kV和3.1cm/kV產品，不僅戶外端耐污性能高，而且盡可能地加大了戶內端的爬電比距，以防止因凝露等原因造成閃絡。
Because the product is more, for ease of user queries, the product classification is introduced respectively. Fouling resistance type series can be divided into two types of Creepage distance ≤2.0cm/kV and ≥2.5cm/kV. Particularly recommended creepage distance 2.5 cm/kV and 3.1 cm/kV products. Not only outdoor side fouling resistance is high, but also increased than indoor the creepage distance as far as possible, in order to prevent the flashover caused by condensation, etc.
高壓穿牆套管製造依據Product manufacturing basis
