產品介紹
35Kv Indoor-Outdoor Antifouling Type wall bushing
35kV戶內戶外耐污型高壓穿墻套管
CWW-40.5/3150-4高壓防污型銅導體穿墻套管，高原型，大爬距，高強度。CWW-40.5/3150-4高壓穿墻套管。外形及安裝尺寸圖Appearance and installation dimensions
CWW-40.5/3150-4 Copper Conductor Wall Bushing
電站用穿墻套管適用于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，墻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.
二、產品分類Product categories
電站用高壓穿墻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墻套管三種結構，并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.
由于產品較多，為便于用戶查詢，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*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.
三、產品制造依據Product manufacturing basis
高壓穿墻套管性能符合GB12944.1-91《高壓穿墻套管技術條件》、GB12944.2《高壓穿墻套管尺寸與特性》的規定。
High pressure wall bushing Performance conforms to GB12944.1-91 High pressure wall bushing technology conditions and GB12944.2 High pressure wall bushing size and characteristics.
