2. Main Characteristics of YDF Series Prefabricted Branch Cable

2.1 Excellent and Reliable Power Supply
2.1.1 main cable conductor has no contact, good continuous and reduce fault point.
2.1.2 branch contact uses mechanical production, reducing poor quality phenomenon.
2.1.3 reasonable structure, using LYZ technology, small touch electrode, not affected by expansion and contraction
2.1.4 complete compressed sheath in short time, avoid touch resistance change caused by copper core exposure to air for a long time
2.1.5 strict technical standard and testing requirement, good quality assurance system

2.2 Simple Installation, Low Environmental Requirement, Convenient Construction
2.2.1 small size, facilitate construction area application
2.2.2 low environmental requirement and installation precision
2.2.3 convenient and simple installation, short cycle, busway 1/10 or 1/20, small installation labor strength
2.2.4 small bending radius, reducing installation difficulties and space

2.3 Good Earthquake Resistance, Air Tightness, Waterproof and Fire-resistant
2.3.1 excellent earthquake-resistant, YDF series prefabricated cable not affected by shock, no any measurement
2.3.2 great air tightness and waterproof, power supply in wet environment, also used in outdoor and road laying
2.3.3 using "NH" prefabricated cable, during burning, maintain 90min normal power supply

2.4 Maintenance-free
2.4.1 according to regular installation, prefabricated cable has high open rate
2.4.2 no need any maintenance

2.5 Reduce Electricity Distribution Cost
2.5.1 compared to busway, reducing construction cost, with high technical indicator and comprehensive economic

2.6 Diversified Types, Flexible
2.6.1 main cable from 10mm³ to 1200mm³, prefabricated cable from 4mm³ to 300mm³
2.6.2 diversified cable types, such as VV, ZR-VV, NH-VV, YJV, ZR-YJV, NH-YJV, SCIA-CE, SC3A-CV, SC1-FPB-CE, SC3-FPB-CV, GZR-YJV, GDL-YJV, GWL-YJE, GNH-YJV, GNH-YJE
