ASTM Standard 25kV XLPE Insulated MV Middle Voltage Power Cable

Application

25kV CU 133% TRXLPE Full Neutral LLDPE Primary used for primary underground distribution in conduit systems suitable for use in wet or dry locations, direct burial, underground duct, and where exposed to sunlight. To be used at 25,000v or less, conductor temperatures not to exceed 90°C during normal operation.

Construction

Conductor: Class A or B Compressed concentric stranded aluminum alloy, Aluminium or copper conductor. Stranded conductors are water-blocked with conductor filling compound.Conductor Shield: Extruded thermosetting semiconducting shield which is free stripping from the conductor and bonded to the insulation.Insulation: Extruded, unfilled Tree-Retardant Cross-linked Polyethylene (TR-XLPE) as defined in ANSI/ICEA S-94-649 - 133% insulation level.Insulation Shield: Extruded thermosetting semiconducting shield with controlled adhesion to the insulation providing the required balance between electrical integrity and ease of stripping.Metallic Shield: Solid bare copper wires helically applied and uniformly spaced.Water Block: Water-blocking agents applied over the insulation shield and around the neutral wires to resist longitudinal water penetration. Longitudinal water penetration shall be tested in accordance with the latest edition of ICEA T-34-664 except that the minimum requirement is 15 psig for 1 hour.Jacket: Linear Low Density Polyethylene (LLDPE) Jacket, black with red extruded stripes.
