Electric Utility Medium-Voltage Power Cable EmPowr® Underground Distribution and Shielded Power Cables General Cable’s EmPowr® underground distribution and shielded power cables are manufactured and tested in accordance with CSA C68.5 for copper concentric neutral, copper flat strap, copper wire, copper tape and longitudinally applied corrugated copper tape (LACT) shielded power cable designs for distribution utilities. Other shielded power cable designs manufactured and tested in accordance with CSA C68.10 are available. Our cables may also meet the latest requirements of AEIC CS8 as applicable. Stranded conductors are Class B compact (4 AWG to 1000 kcmil) 3/4 to full hard 1350 aluminum. Conductors are also available in solid, class B compressed or compact concentric-lay-stranded aluminum or copper, meeting the appropriate requirements of ASTM and CSA. Stranded conductors can be blocked to prevent longitudinal penetration of water along the cable. When applicable, STRANDFILL® T-31-610. conductors are tested in accordance with ICEA 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. Designs are manufactured with either lead-free Tree-Retardant Cross-linked Polyethylene (TRXLPE), Ethylene Propylene Rubber (EPR) or lead-free EAM insulation. Our EmPowr® is an economical option for the high-volume usage in underground residential systems. Our EmPowr® Fill EPR insulated cables are flexible for easy handling and exhibit excellent heat and moisture resistance. The physical and thermal characteristics of EPR insulation result in a high resistance to deformation. EPR insulation is typically specified for heavily loaded circuits such as feeders and network systems. Cables are available with various metallic shields that include round wires (16 AWG or 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® water-blocked cables are tested in accordance with ICEA T-34-664. 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™ maintains the same physical properties of EmPowr® providing excellent resistance to deformation. EmPowr® Link CL™ 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™ Link LLDPE jacket constructions but with enhanced thermomechanical performance meets the latest requirements of CSA C68.5 and AEIC CS8 as applicable for TRXLPE. is rated for 105˚C maximum conductor temperature under normal conditions in accordance with CSA C68.5. This design option has been particularly successful for renewable energy collection systems. 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 and 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® in today's aging and expanding urban underground distribution systems of utilities where PILC has been used previously. Our unique PowrPak® to be installed into existing ductwork, which is not always possible with other types of PILC replacement cable. cables are intended for use design and special manufacturing techniques allow a diameter reduction of more than 15 percent relative to standard CSA solid dielectric cables. The smaller diameter permits PowrPak® 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 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 inquires.
