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.

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).
