[pdf] [/pdf] [short] Aluminum Conductor 25KV URD – 1/3 Neutral 100% Applications: 25kV cable is an electrical wire and a medium voltage cable, installed through direct burial or in conduit, for underground distribution. 25kV aluminum urd cable is used in both wet and dry locations at a maximum of 25,000V. The maximum temperature for this electrical cable is 90°C. Also Known As: 25kv cable, medium voltage cable, medium voltage wire, bury cable, direct burial cable, direct burial power cable, medium voltage power cables, aluminum direct burial cable, aluminum urd cable, urd direct burial cable. Standards: ASTM B-3, B-8, B230, B-231, B-609 ANSI/ICEA S-94-649 AEIC CS-8 RUS ACCEPTED For 90°C continuous, 130°C emergency and 250°C short-circuit operation Construction Conductors: 25kV cable aluminum conductor is made of 1350 aluminum series, which is solid or compressed and soft drawn stranded in accordance with ASTM. The conductor has a filling compound and is water-blocked. Insulation: The 25kV aluminum urd cable has TR-XLPE insulation, which offers high dielectric strength. EPR insulation is also available. Metal shield: The metal shield is concentric neutral and consists of solid bare copper wires that cover the insulation shield. Jacket: The 25kV cable jacket is black color coded for simpler identification and consists of linear lows density polyethylene (LLDPE). The jacket offers protection from heat, sunlight, and abrasion. [/short] Frequently Asked Questions - Aluminum conductor 15kv mv105 What are the temperature specifications of the Aluminum conductor 15kv mv105? The Aluminum conductor 15kv mv105 can be used continuously at 105°C. It can withstand 140°C when it is a case of emergency overload and even 250°C for short circuit conditions. What are the common applications that the Aluminum conductor 15kv mv105 is used for? This cable is suitable for both wet and dry locations where direct burial is required. It can also be installed in underground ducts and open air. It can be used in power circuits that require15,000 volts or less. What is the advantage of using aluminum conductor for this cable? Aluminum conductors are light weight when compared to copper cables. It is easier and more flexible to work with which greatly improves the job efficiency. Aluminum conductors are preferred for use in great distances as iteasy to install and maintain. Copper conductors of the same specifications would require more support for the cable to be secured. Do I have to be worried about “cold creep” when I use this aluminum conductor? “Cold creep” or “cold flow” is the instance where the elasticity of the conductor is affected slowly over a period of time. Usually the conductor expands when it is warm and contracts when it is cold. However, with each warm and cool cycle, there is a reduction in the tightness of the wiring which may result in loose connections. However, this phenomenon can be reduced when the wires are installed properly and with regular maintenance. How is the Aluminum conductor 15kv mv105 constructed? It comes with 1350 series Aluminum for the conductor with Class B stranding as per ASTM standards. When it is mentioned 15kv, then the cable would require a shield. The insulation can be EPR-based in accordance with ICEA S-97-682 and it has semi-conducting properties. Finally, it is covered with either a PVC or an EPR jacket. What does the “MV” stand for inAluminum conductor 15kv mv105? MV stands for medium voltage which is in accordance with UL 1072. MV cables are generally used as the primary power feeder in all kinds of commercial and electrical projects. MV cables can be used in both wet and dry locations. What are the various factors that the cable is resistant to? The Aluminum conductor 15kv mv105has a sunlight resistant jacket and a heat and moisture resistant insulation. The cable has passed the IEEE 383 flame test and the IEEE 1202 flame test.
