Overhead (OH) service drop cable consists of one, two or three aluminum conductor insulated with extruded lead-free Cross-linked Polyethylene (XLPE), twisted around a bare conductor which serves as a supporting neutral. Service drop cable meets the requirements of ANSI/ICEA S-76-474. Conductors meet ASTM B231, B232 and B399 as applicable. Their use should be limited to circuits not exceeding 600 volts phase-to-phase and a 90°C normal conductor temperature.
Phase conductors are circular stranded aluminum (AAC).
The standard insulation on the phase conductors is black low-density crosslinked polyethylene (XLPE).
Alternatively, black linear low-density polyethylene (LLDPE) insulation with a 75°C temperature rating is available upon request.
The XLPE insulation meets the requirements of ANSI/ICEA S-76-474-2004 (Standard for Neutral-Supported Power Cable Assemblies with Weather-Resistant Extruded Insulation Rated 600 Volts).
The LLDPE insulation meets the requirements of ASTM Standard D1248-05 (Standard Specification for Polyethylene Plastics Molding and Extrusion Materials).
The all-aluminum stranded conductors are Class AA or Class A 1350-H19 (AAC) or 6201- T81 alloy (AAAC). The aluminum conductor steel reinforced (ACSR) is Class AA. The direction of lay of the outer layer is right-hand.
The insulated phase conductors are twisted around the bare neutral conductor with a right-hand lay length of 25 to 60 times the diameter of one phase conductor.
►In electric power distribution, a service drop is an overhead electrical line running from a utility pole, to a customer's building or other premises.
►It is the point where electric utilities provide power to their customers.
►The insulated conductors of service drop cables are resistant to weathering, sunlight, abrasion, tearing, cutting and chemicals. This cable is rated at 600 volts with a maximum conductor operating temperature of 90°C for cross-linked polyethylene insulation.
►Ease of erection and stringing.
►Practically no tree-trimming required.
►Relative immunity to short circuits caused by external forces (wind, fallen branches), unless they abrade the insulation.
