Electric Utility Medium-Voltage Power Cable Medium-Voltage Power Cable EmPowr® Underground Distribution and Shielded Power Cables S-94-649 for copper concentric neutral and flat strap power cable designs or ANSI/ICEA S-97-682 for copper wire, copper tape and longitudinally applied corrugated copper tape (LACT) shielded power cable designs. Our cables also meet the latest requirements of AEIC CS8 and/or RUS U1 as applicable. Stranded conductors are Class B compressed 1350-H19 aluminum. Solid conductors are H16 temper. Conductors are also available in solid, Class B compressed or compact concentric-lay-stranded aluminum or copper, meeting the appropriate requirements of ASTM. Stranded conductors can be blocked to prevent longitudinal movement of moisture along the cable. When applicable, STRANDFILL® tested in accordance with ICEA T-31-610. conductors are Exceptional measures are taken during the materials handling and extrusion processes to ensure our cable delivers the reliability and longevity expected by our customers. All compounds are received and handled in an ultra-clean environment. Compounds are received in specially designed ultra-clean containers (protective outer box with a sealed removable inner lining) and handled within Class 10,000 conditions. In addition to the special materials handling, the conductor shield, insulation and insulation shield are applied using triple extrusion technology. These extra measures provide our customers with the highest-quality cable products available in the industry. EPR and lead-free EAM insulated cables are flexible for easy handling and exhibit excellent heat and moisture resistance. The physical and thermal characteristics of EPR and lead-free EAM insulation result in a high resistance to deformation. EPR and lead-free EAM insulation is typically specified for heavily loaded circuits such as feeders and network systems. characteristics. TRXLPE insulation is an economical option for the high-volume usage in underground residential systems. Our EmPowr® Designs are manufactured with either lead-free Tree-Retardant Cross-linked Polyethylene (TRXLPE), Ethylene Propylene Rubber (EPR) or lead-free EAM insulation. Our EmPowr® Link TRXLPE insulated cables offer high dielectric strength with extremely low dielectric loss Fill Cables are available with various metallic shields that include round wires (16 AWG and larger), helically applied copper tape, flat copper straps or longitudinally applied corrugated copper tape. Combinations of water-swellable tapes and powders applied between the insulation shield and jacket provide maximum moisture migration protection. When applicable, BIFILL® ICEA T-34-664. water-blocked cables are tested in accordance with Standard designs are manufactured with black, non-conducting, sunlight-resistant Linear Low-Density Polyethylene (LLDPE). Jacketed cables are rated for 90˚C maximum conductor temperature under normal conditions. General Cable’s EmPowr Link CL™ TRXLPE insulated XLPE jacketed cables allow reduced-size copper concentric neutrals while still providing fault current of an LLDPE jacket, leading to cooler operation and lower line losses. EmPowr Link CL maintains the same physical properties of EmPowr Link LLDPE jacket constructions but with enhanced thermomechanical performance providing excellent resistance to deformation. EmPowr Link CL meets the latest requirements of ANSI/ICEA S-94-649 and AEIC CS8 as applicable for TRXLPE. EmPowr Link CL is rated UL MV-105 in accordance with UL 1072 for 105˚C maximum conductor temperature under normal conditions. This design option has been particularly successful for renewable energy collection systems. General Cable has introduced the EmPowr Link CL ADVANTAGE product line, which takes the EmPowr Link CL product to a further enhanced level of refinement and cost saving. The combination of a compact phase conductor and flat strap neutrals provides a lighter weight cable with an overall smaller diameter for longer cable lengths and highly efficient fault current protection. A growing alternative to direct buried cable or pulling cable in rigid conduit is purchasing cable pre-installed in flexible duct. Our Combined Duct & Cable offers mechanical protection comparable to rigid polyethylene duct and saves the labor of pulling cable into rigid duct. Combined Duct & Cable can also save considerable costs associated with cable replacement as compared to direct buried cable installations. General Cable provides a number of underground cables designed to meet special applications. For example, our PowrPak® intended for use in today’s aging and expanding urban underground distribution systems of utilities where PILC has been used previously. Our unique PowrPak design and special manufacturing techniques allow a diameter reduction of more than 15 percent relative to standard AEIC solid dielectric cables. The smaller diameter permits PowrPak to be installed into existing ductwork, a feat not always possible with other types of PILC replacement cable. While General Cable manufactures a complete range of primary concentric neutral power cables, only the most popular designs are described in the following section. Details of other constructions, voltages and sizes are available upon request. General Cable provides technical assistance and advice on any challenges associated with cable design, installation or application. Engineering services are available for specification review, specification development and cable application inquiries.
