Number 2 triplex cable is typically good for 150 amps. This ampacity is associated with common types of aluminum triplex overhead service drop cable, specifically those with a 2-2-2 gauge configuration, often used for residential and commercial electrical service.
Understanding Number 2 Triplex Cable
When referring to "number 2 triplex," it generally indicates a cable composed of three conductors, often in a 2-2-2 gauge arrangement, commonly seen in aluminum overhead service drop applications. This type of cable is designed to deliver power from utility poles to buildings. Its construction and material properties, such as the use of aluminum conductors and robust insulation, determine its current-carrying capacity or ampacity.
This specific type of triplex cable is engineered for reliability and safety in outdoor environments. Its design ensures it can withstand various weather conditions while maintaining efficient power delivery.
Key Specifications for Number 2 Triplex Overhead Service Drop Cable
For a typical 2-2-2 aluminum triplex overhead service drop cable, key electrical and physical specifications include:
| Feature | Specification |
|---|---|
| Ampacity | 150 Amps |
| Voltage Rating | 600 Volts |
| Insulation Material | XLPE (Cross-linked Polyethylene) |
| Sunlight Resistance | Yes |
The ampacity of 150 amps means that the cable can safely carry a continuous current of up to 150 amperes without overheating or sustaining damage under normal operating conditions. The 600-volt rating indicates its suitability for standard low-voltage distribution systems. The XLPE insulation provides excellent dielectric strength, heat resistance, and durability, while its sunlight resistance ensures longevity when exposed to UV radiation outdoors.
Applications of Triplex Cable
Triplex overhead service drop cables are essential components in electrical distribution infrastructure. Their primary applications include:
- Residential Service Entrances: Delivering power from the utility's service drop to the meter base on homes.
- Commercial Buildings: Providing electrical service to smaller commercial establishments.
- Outdoor Lighting Circuits: Supplying power to streetlights and other outdoor lighting systems where overhead wiring is utilized.
- Temporary Power Connections: Used for construction sites or events requiring temporary overhead power.
The robust construction and specific ampacity of number 2 triplex make it a versatile choice for a wide range of overhead power delivery needs, ensuring safe and efficient electrical distribution.
