Product Description

Product overview

The Aluminum RHH/RHW-2/USE-2 350 MCM cable is a versatile, single-conductor, cross-linked polyethylene (XLPE) insulated wire rated for 600 volts and designed for both above-ground and underground low-voltage power distribution. Manufactured with a compact stranded AA-8000 series aluminum conductor, this cable provides an excellent balance of performance, durability, and cost-effectiveness.

With its dual-rated construction (RHH/RHW-2/USE-2), the cable is suitable for dry, wet, and direct burial applications, making it ideal for utility services, residential feeders, and branch circuits. The XLPE insulation ensures high thermal stability, moisture resistance, and dielectric strength, allowing operation at 90°C in both wet and dry locations.

Specification

Applications

USE-2: Commonly used for underground service entrance (USE), especially in direct burial installations without conduit. Approved for wet or dry environments with conductor temperatures up to 90°C.
RHW-2: Suitable for use in conduit or raceways in wet or dry locations. Ideal for industrial, utility, and outdoor feeders.
RHH: Intended for dry locations only, used in raceways or conduit, such as switchgear, distribution panels, and indoor feeders.

Key Features

Conductor: Compact stranded aluminum alloy (AA-8000 series) for excellent conductivity and lightweight performance.
Insulation: Cross-linked polyethylene (XLPE) insulation offers high thermal resistance and moisture protection.
Voltage Rating: 600V
Temperature Rating: 90°C in both wet and dry environments.
Sunlight Resistant: UV-resistant insulation makes it suitable for outdoor exposure.
Flame Retardant: Meets UL 44 flame test requirements for RHH and RHW-2 applications.
Direct Burial Rated: Certified for direct burial without conduit in accordance with USE-2 standards.
Cost-Efficient: Aluminum conductor provides a more economical solution compared to copper with good conductivity.

FAQ

Q1: What does "RHH/RHW-2/USE-2" mean?
A: These are UL designations for the environments the cable is approved for:

RHH: Dry locations
RHW-2: Wet or dry locations at 90°C
USE-2: Direct burial and underground service entrance

Q2: Can this cable be buried directly underground?
A: Yes, it is rated USE-2, which means it is approved for direct burial in the earth without a conduit.

Q3: Is this cable suitable for indoor use?
A: Yes. As an RHH or RHW-2 cable, it can be used indoors in raceways or conduit.

Q4: What are the advantages of aluminum conductors?
A: Aluminum is significantly lighter and more cost-effective than copper, making it easier to handle and install for long runs or large projects.

Q5: Can this cable be exposed to sunlight?
A: Yes. It is UV-resistant and suitable for outdoor use.

Q6: What standards does this cable meet?
A:UL 44 for RHH/RHW-2
UL 854 for USE-2
NEC Articles 310 and 338

Q7: Is this cable flexible enough for conduit bending?
A: Yes, the compact stranded aluminum construction provides adequate flexibility for conduit and raceway installation.

Q8: Can this cable be installed in cable trays?
A: No, it is not rated for installation in cable trays.
