電纜型號解析

WDZB1-YJY-0.6/1kV 3*95+2*50是一種特定類型的電力電纜，下面對該型號的各個組成部分進行詳細的解釋：

1、 WDZB1

W: 無鹵 (Low Halogen Free)

D: 低煙 (Low Smoke)

Z: 阻燃 (Flame Retardant)

B1: 阻燃等級為B1級 (Fire Resistance Level B1)

2、 YJY

YJ: 交聯(lián)聚乙烯絕緣 (Cross-linked Polyethylene Insulation)

Y: 聚烯烴護套 (Polyolefin Sheath)

3、 0.6/1kV

額定電壓為0.6/1kV，表示電纜的相間電壓為1kV，相對地電壓為0.6kV (Rated Voltage 0.6/1kV)

4、 3*95+2*50

3*95:3根主線芯，每根線芯的截面積為95平方毫米 (Three Main Conductors, each with a Cross-sectional Area of 95 Square Millimeters)

2*50:2根輔助線芯（如中性線和接地線），每根線芯的截面積為50平方毫米 (Two Auxiliary Conductors, such as Neutral and Ground, each with a Cross-sectional Area of 50 Square Millimeters)

電纜結(jié)構(gòu)詳解

導(dǎo)體 (Conductors):

通常由多股銅絲絞合而成，提供良好的導(dǎo)電性和柔韌性 (Typically made from Stranded Copper Wire for Good Electrical Conductivity and Flexibility)

主導(dǎo)體數(shù)量為3根，截面積為95平方毫米 (Main Conductors: Three in Number, 95 Square Millimeters Each)

輔助導(dǎo)體為2根，截面積為50平方毫米 (Auxiliary Conductors: Two in Number, 50 Square Millimeters Each)

絕緣層 (Insulation Layer):

采用交聯(lián)聚乙烯 (XLPE, Cross-linked Polyethylene)，具有優(yōu)良的電氣絕緣性能和耐溫性能 (Uses XLPE, which has Excellent Electrical Insulation and Heat Resistance Properties)

絕緣層厚度依據(jù)電纜的額定電壓和導(dǎo)體截面積確定 (Thickness Determined by Rated Voltage and Conductor Cross-sectional Area)

護套 (Sheath):

采用聚烯烴材料，具有低煙無鹵和阻燃特性 (Made from Polyolefin Material with Low-smoke, Halogen-free, and Flame-retardant Properties)

提供額外的物理和化學(xué)保護，防止外部環(huán)境對電纜的影響 (Offers Additional Physical and Chemical Protection against Environmental Factors)

應(yīng)用場景

這類電纜主要用于對阻燃和環(huán)保性能要求較高的場所，如：

高層建筑 (High-rise Buildings)

地鐵 (Subways)

機場 (Airports)

醫(yī)院 (Hospitals)

大型商場 (Large Shopping Malls)

會展中心 (Exhibition Centers)

數(shù)據(jù)中心 (Data Centers)

交通樞紐 (Transportation Hubs)

這些場所往往人員密集，對電纜的安全性能有嚴格的要求 (These places are often densely populated and have stringent safety requirements for cables).

技術(shù)標(biāo)準(zhǔn)

該電纜的技術(shù)參數(shù)和性能要求通常符合以下國家和國際標(biāo)準(zhǔn)：

GB 31247-2014

GB/T 12706.1-2008

GB/T 19666-2019

這些標(biāo)準(zhǔn)規(guī)范了電纜的電氣性能、機械性能、阻燃性能和環(huán)保性能 (These standards regulate the electrical, mechanical, flame retardant, and environmental performance of the cable).
