3/0 AWG Amherst Aluminum Alloy 6201-T81 Concentric Round Covered Shield Polyethylene 15KV Tree Wire

Allowable Ampacity for 3/0 AWG Amherst Aluminum Alloy 6201-T81 Concentric Round Covered Shield Polyethylene 15KV Tree Wire:100 Amps

About:

Tree wire or covered open wire consists of the conductor (aluminum, aluminum alloy or ACSR ) and the extruded covering (conductor shield, low density inner layer and protective outer layer). Covering thickness depends on the system voltage. Itis designed for full span applications and is supported on polyethylene insulators. We also offer a two layer covered conductor design for 15kV systems that are not subject to heavy tree contact. Covered conductors are available in black or gray depending on visual preference.

Also Known As:

• 15kV Tree Wire or 15kV Covered Aerial MV (Medium Voltage) Cable: Reflecting its insulation level and typical use in medium-voltage overhead power lines.
• 3/0 AWG Spacer Cable: Denoting its gauge size and its use in systems where spacers keep the cables apart.

Application:

Hendrix provides tree wire designed for systems from 15kV through 46kV. Polyethylene insulators must be used to insure dielectric compatibility with conductor covering. Conductors are supported on crossarms or standoff brackets. Span lengths are limited by the conductor breaking strength and the amount of sag that is permissible. Covered conductors are rated for continuous operation at 75°C. (Consult Hendrix sales representative for 46kV tree wire systems).

Benefits:

• Covering prevents faults due to contact
• Proprietary, high density outer layer resists abrasion, electrical tracking and UV degradation.
• Reduced NESC phase spacing is possible due to high impulse strength covering.
• Pole hardware is the same as bare wire construction except that Hendrix polyethylene insulators are required.

Standards:

• ASTM B398: This specifies the technical details for Aluminum-Alloy 6201-T81 wire for electrical purposes, ensuring the wire's quality and performance.
• ASTM B230: It defines the standard for aluminum 1350-H19 wire for electrical purposes, which might be relevant for the aluminum used in the construction of this wire.
• ANSI/ICEA S-76-474: This standard covers the requirements for neutral-supported power cable assemblies with weather-resistant extruded insulation for voltages from 5 kV to 46 kV, which includes 15kV tree wire.

Construction:

• Conductor: Utilizes 3/0 AWG Aluminum Alloy 6201-T81, offering a balance of strength and electrical conductivity ideal for medium-voltage applications.
• Insulation: The wire is covered with a layer of black cross-linked polyethylene (XLPE) or high-density polyethylene (HDPE), rated for 15kV to provide electrical insulation and physical protection.
• Shield: A concentric neutral wire shield is applied over the insulation, typically consisting of aluminum, aluminum alloy, or sometimes galvanized steel wires, to provide fault current return path and additional mechanical protection.
• Jacket: An outer jacket of polyethylene provides resistance against UV, weathering, abrasion, and other environmental stresses.

Features:

• Electrical Performance: Designed for 15kV applications, ensuring reliable power distribution at medium voltages.
• Mechanical Durability: The aluminum alloy conductor offers superior tensile strength compared to pure aluminum, withstanding mechanical stresses during installation and service.
• Environmental Resistance: The polyethylene insulation and jacket provide excellent resistance to UV light, moisture, chemicals, and temperature variations, ensuring a long service life even in challenging conditions.
• Safety and Reliability: The covered design minimizes the risk of outages caused by contact with trees or wildlife and enhances safety by preventing accidental contact with the energized conductor.
