Cables by Type

Service Drop Cable

Service drop cable is an overhead electrical line that extends from a utility pole to a customer's building or service entrance. It delivers electrical power from the distribution network to individual homes or businesses. These cables are mainly with three types: Duplex Service Drop Wire, Triplex Service Drop Wire and Quadruplex Service Drop Wire.

Duplex Service Drop Wire: Duplex service drop aluminum conductors are designed to supply 120-volt aerial service for various applications, including temporary services at construction sites and outdoor or street lighting. They are also suitable for permanent installations operating at 600 volts or lower, with a maximum conductor temperature of 75°C. These conductors are ideal for settings where reliability and ease of installation are critical.

Triplex Service Drop Wire: Triplex service drop aluminum conductors are used to deliver electrical power from utility lines to the consumer's weatherhead. These conductors are designed for service applications at 600 volts or less (phase to phase) with a maximum conductor temperature of 75°C for polyethylene insulation or 90°C for cross-linked polyethylene (XLPE) insulation. They are commonly employed in residential and commercial installations for safe and reliable power distribution.

Quadruplex Service Drop Wire: Quadruplex service drop aluminum conductors are intended for supplying three-phase power, typically from a pole-mounted transformer to the user's service head, where they connect to the service entrance cable. These conductors are suitable for applications at voltages of 600 volts or less (phase to phase) and can operate at conductor temperatures up to 75°C for polyethylene-insulated conductors or 90°C for XLPE-insulated conductors. They are ideal for residential, commercial, and light industrial power distribution.

Construction

● Cores: Conductors are typically made of aluminum due to its lower cost and lighter weight. The construction generally includes a neutral messenger and one or more phase conductors. The neutral messenger provides support and serves as a grounding conductor.

● Insulation: The phase conductors are insulated to protect against electrical faults and environmental factors. The neutral messenger may be bare or insulated, depending on the specific design.

Standard

ANSI/ICEA S-76-474

1. Title: Standard for 600 V and 1000 V, 90°C Thermoplastic Insulated Power Cables for Use in Industrial and Commercial Applications

2. Scope: ANSI/ICEA S-76-474, developed by the American National Standards Institute (ANSI) and the Insulated Cable Engineers Association (ICEA), outlines the specifications for thermoplastic insulated power cables designed for use in industrial and commercial environments. The standard covers cables rated for 600 volts and 1000 volts with a maximum operating temperature of 90°C. It provides detailed requirements for cable construction, insulation materials, and performance characteristics to ensure reliability, safety, and compliance with industry standards.
