FAQ From Customers
-
What is a service drop cable?
A service drop cable is an electrical cable that connects overhead power lines from the utility's distribution system to a residential or commercial building’s main electrical panel. Typically made of aluminum or copper, the cable serves as the final connection between the utility provider and the consumer, delivering electricity safely and reliably. It is often used for low-voltage power distribution to homes and businesses. -
What is a drop cable used for?
A drop cable is used to connect electrical service lines from a utility pole or transformer to the customer’s property. It provides the final connection for residential or commercial electrical service. Drop cables can be overhead service drop cables or underground service cables, depending on the installation method. These cables ensure safe and efficient delivery of electricity from the electricity distribution network to the meter and main breaker panel of a building. -
What type of wire is used for a service drop?
The type of wire used for a service drop depends on the voltage and installation method. Commonly, aluminum conductors are used in overhead service drop cables because of their lightweight and high conductivity. Duplex, triplex, and quadruplex cables are typically used, with triplex cables often being the most common for three-phase systems. These wires are designed to withstand environmental stress and provide safe power distribution for residential connections. -
What is an overhead service drop cable?
An overhead service drop cable is a type of drop cable that connects the utility pole to the house or building through overhead power lines. This cable is usually aluminum or copper and is designed to carry low voltage electricity from the distribution network to the customer's property. Overhead service drop cables are commonly used in residential areas and can be subjected to weather and environmental challenges, so they are built with durable, weather-resistant materials. -
What is the difference between Duplex, Triplex, and Quadruplex service drop cables?
Duplex, triplex, and quadruplex service drop cables differ in their construction and use:
1. A duplex cable consists of two wires and is typically used for single-phase connections in residential service drops.
2. Triplex cable includes three conductors and is used for three-phase connections, commonly in larger residential or commercial installations.
3. Quadruplex cable includes four wires and is used for three-phase service with an additional neutral conductor. This makes it ideal for larger, more complex service drops and higher voltage applications. Each cable type provides reliable electrical service and safe connections between the utility and the building.
