ASTM Standard Middle Voltage Power Cable

15kV CU 133% TRXLPE Fully Neutral LLDPE is mainly used for primary underground power distribution in pipeline/conduit systems, suitable for use in wet or dry place, direct burial, underground pipeline, and locations exposed to sunlight. When used at voltage of 15,000v or lower, the conductor temperatures not to exceed 90°C during normal working.

25kV cable is suitable for use in wet and dry areas, conduits, ducts, trenches, trays, direct burial and where electrical performance is superior when installed closely with a grounded conductor complying with NEC Sections 311.36 and 250.4(A)(5) Properties are required. The cables are capable of continuous operation at conductor temperatures not exceeding 105°C in normal operation, 140°C in emergency overload conditions, and 250°C in short-circuit conditions. Cold bend rated to -35°C. ST1 (Low Smoke) is rated for sizes 1/0 and larger. The PVC sheath is made with SIM technology and has a coefficient of friction COF of 0.2. The cable can be installed in the conduit without lubrication. Rated for maximum sidewall pressure of 1000 lb/ft.

35kV CU 133% TRXLPE Fully Neutral LLDPE is mainly used for primary underground power distribution in conduit systems, suitable for wet or dry locations, direct burial, underground duct and places exposed to sunlight. Normal operation uses voltages of 35,000v or less, conductor temperatures not exceeding 90°C during normal operation.
