交聯(lián)聚乙烯絕緣電力電力，具有高機械強度、耐環(huán)境應力好、優(yōu)良的電氣性能和耐化學腐蝕等特點，產品重量輕，結構簡單，使用方便。本產品適用于額定電壓0.6/1 kV輸配電系統(tǒng)，供輸配電能之用。
阻燃型電纜的主要特點是電纜不易著火，或著火時延燃僅局限在一定范圍內，適用于電纜敷設密集程度比較高的發(fā)電站、地鐵、隧道、高層建筑、大興工礦企業(yè)、油田、煤礦等場所。
耐火型電纜的主要特點是除了能在正常的工作條件下傳輸電力外，電纜在著火燃燒時仍能保持一定時間的正常運行。適用于核電站、地鐵、隧道、高層建筑等與防火安全和消防救生有關的場所。
XLPE insulated power cables, which has high mechanical robustness, good environmental stress, excellent electrical properties and chemical resistance characteristics, is simple in structure ,light in weight and convenient in applicable. This product is suitable for rated voltage of 0.6/1 kV power distribution system, for transmission and distribution of electric energy use.
The main features of flame retardant cable is not easy to catch fire,or it can confine the fire in some limited area. There fore the cable is applicable to the places where the density of cable laying is high,such as generating stations, subways, tunnels, high-rise buildings, large industrial and mining enterprises, oil field, coal mine and other places.
The fire-resistant cable is besides the power transmission under normal condition, can continue operating normally for some time when it catches fire,so it is applicable to the place which is concerned to the fires safety and fire rescue,such as nub power plant,subway,tunnel,high-rise building and so on.
