CONSTRUCTION:
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.
1.Phase conductor
Phase conductors are circular stranded aluminum (AAC).
2.Phase insulation
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).
3.Neutral conductor
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.
4.Assembly
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.
FEATURES
?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
?Less maintenance
?Relative immunity to short circuits caused by external forces (wind, fallen branches), unless they abrade the insulation.
