Overhead conductor AL 1x35 7x2.52ADt AL-1X35

Aluminum Aerial Conductor – Reliability and Durability

The aluminum conductor AL 1x35, with a cross-section of 35 mm², is an element designed for the construction of overhead lines. Made of high-quality aluminum, it provides effective and safe transmission of electrical energy. The conductor's construction, based on stranded wires, guarantees flexibility and resistance to mechanical damage.

Construction and Application

The AL-1X35 conductor consists of a single aluminum core, stranded with seven wires with a diameter of 2.52 mm (7x2.52ADt). This construction provides adequate flexibility while maintaining high mechanical strength. This conductor is ideal for use in the power industry, especially in places requiring a reliable and durable solution. It finds application in overhead lines, where resistance to weather conditions and mechanical loads is essential.

Key Features and Benefits

• Aluminum as a core material: Provides good electrical conductivity with a relatively low weight – which translates to easier installation and lower load on supporting structures.
• Stranded wire construction: Increases the flexibility of the conductor, making it easier to lay and minimizing the risk of damage during installation and operation.
• Mechanical resistance: The twisted wire construction provides high tensile strength and other mechanical loads, which is crucial for overhead conductors exposed to wind and other external factors.
• Lack of insulating coating: This characteristic means that this conductor is intended for use in places where insulation is not required or poses an additional hazard (e.g., short circuit with the supporting structure).
• Compliance with PN-EN 1715-2:2000 standard: Confirms high quality of workmanship and compliance with applicable safety standards.
• Available technical data: Allows precise selection of the conductor for specific installation needs – knowing the nominal cross-section (35 mm²) and breaking strength (5429 N) allows you to select appropriate fixing elements.

Parameters for Professionals

The AL 1x35 conductor is characterized by a nominal cross-section of 35 mm² and an approximate diameter of 7.55 mm. The calculated resistance of 1 km of conductor at 20°C is 0.838 Ω and its approximate weight is 96 kg/km. This data is crucial for designers and installers when selecting appropriate protection and fixing elements. The conductor construction is based on 7 wires with a diameter of 2.52 mm, which affects its flexibility and mechanical strength.
