USE-2 cables are primarily used for power distribution, in raceways in accordance with National Electrical Code, except that the cable is not rated for use in cable tray. USE-2 is approved for direct burial and for service entrance below ground. USE-2 cables may be used in wet or dry locations, with ambient temperatures not exceeding 90°C. Voltage rating for USE-2 cable is 600V.
USE-2 conductor is a compact soft drawn bare 8000 series aluminum, with Class B stranding per ASTM
USE-2 has abrasion, heat and moisture resistant cross-linked polyethylene insulation XLPE
- USE-2 meets or exceeds the following standards
- UL 44
- Requirements of the National Electrical Code
- ASTM standards B 800, B 801
- Sunlight resistant
- RUS ACCEPTED
ALUMINUM RHH/RHW-2/USE-2 90°C XLPE INSULATION 600V
This type of aluminum cable is also rated at 600 volts just as its name implies. It can operate in temperatures not exceeding 900C. It primarily used for power distribution but cannot be installed in cable trays unlike other types of aluminum cables. It is also heat and moisture resistant.
Aluminum home feeder cable has a compact stranded soft drawn 8000 series aluminum conductor in accordance to ASTM B-800 or B-801. The conductor is the electrode in the cable and is responsible for transmitting electric current.
It has cross-linked polyethylene (XLP) insulation. The conductors are normally cabled together with XLP insulated aluminum ground or bare copper ground and covered with a reinforced binder tape. XLP insulation is tough and is resistant to impact, abrasion, chemicals, acids, oils, industrial solvents and changes in weather.
The cable jacket used in its design is polyvinyl Chloride (PVC). The jacket protects the inner components of the cable from external forces that may cause damage to it. PVC is robust and is resistant to oil, sunlight, water, flames, acids, chemicals, radiation, impact, abrasion and weather changes. On the cable jacket are sequential footage markings that help the user identify the appropriate length during installation without guess work.

Question and Answer:
Frequently Asked Questions - Aluminum RHH/RHW-2/USE-2 90°C
Any special instructions I should follow while using Aluminum RHH/RHW-2/USE-2 90°C?
Aluminum RHH/RHW-2/USE-2 90°C cables are designed for use in power distribution within raceways as per the National Electrical Code. While the cables are not rated to be used in cable tray, they should be used in applications of about 600 volts and you should make sure that the temperatures don’t exceed 90 degrees Celsius.
What are the specifications of Aluminum RHH/RHW-2/USE-2 90°C cables?
The cables are listed UL 44 and meet ASTM standards B 800 and B 801. They also meet the requirements of the National Electrical Code and are RUS accepted.
How can I identify an Aluminum RHH/RHW-2/USE-2 90°C cable?
It has compacted conductors that are made of aluminum alloy AA-8000 series and these conductors have RHH, RHW-2, and USE-2 specifications. When you strip off the insulation of the conductor, you will see that they are made using aluminum material which appears light gray instead of the coppery color you find with copper wires. When you look at the insulation, it is made of cross-linked polyethylene (XLPE).
What does RHH, RHW-2, and USE-2 mean?
Type RHH cable means that it is designed to work in dry locations however, the temperature should not exceed 90 degrees Celsius. With RHW-2, it implies that the cable can be used in both wet and dry locations however, the temperature should not be more than 90 degrees Celsius. USE-2 is therefore suitable for underground services within dry and wet locations but the temperature requirement should not be more than 90 degrees Celsius.
Should I use copper instead of aluminum cable?
In the past, aluminum cables had a tendency of oxidizing after they have been exposed to air and this prevents flow of electricity. The aluminum cables used in the past could often become hot and at times, they could result in fire. This was unsafe, but today, with advancement in the engineering of aluminum cables, they are safe. The aluminum cables designed today have a protective cover to prevent oxidation. Therefore, you can consider using aluminum cables such as Aluminum RHH/RHW-2/USE-2 90°C.
