Precision-engineered from 6061-T6 aluminum alloy, this connecting pipe utilizes a bolted compression design to create secure, low-resistance connections without the need for crimping tools. Compliant with GB/T 14315 and IEC 61238-1 standards, it accommodates conductor cross-sections from 50 mm² to 630 mm² in systems operating up to 20 kV. Its modular design simplifies installation in both overhead and underground applications, making it ideal for utility networks, renewable energy farms, and industrial power systems seeking efficient conductor joining solutions.
Constructed from 6061-T6 heat-treated aluminum alloy, the connecting pipe achieves a tensile strength of 310 MPa and yield strength of 276 MPa, providing exceptional mechanical stability under thermal cycling and vibration. The alloy formulation delivers a conductivity of 55% IACS, ensuring efficient current transfer with minimal power loss.
The pipe features a two-piece clamp design with stainless steel bolts (A2-70 grade) that apply uniform radial pressure across the conductor interface. This creates a gas-tight connection with a contact resistance of ≤10 µΩ, maintaining conductivity even under cyclic loading conditions. The bolted design allows for reusable connections when conductors need to be repositioned or replaced.
The aluminum surface undergoes a hard anodizing treatment (15-20 µm thickness) that provides superior corrosion resistance compared to conventional coatings. This treatment creates a wear-resistant oxide layer that withstands exposure to industrial pollutants, coastal salt spray, and UV radiation, ensuring long-term performance in outdoor environments.
Utility companies utilize the connecting pipe for joining aluminum conductors in overhead distribution lines and underground cable systems, providing reliable connections in both urban and rural power networks. Its lightweight design reduces installation time and structural loading on support structures.
In solar farms and wind energy parks, the pipe connects aluminum collection cables in combiner systems and array wiring, supporting the integration of renewable energy into the main power grid. Its corrosion resistance ensures durability in outdoor renewable energy environments.
The connecting pipe provides flexible conductor joining solutions in industrial facilities, including manufacturing plants, refineries, and processing centers, where it accommodates aluminum conductors in power distribution panels and motor control centers.
Installation requires a torque wrench capable of delivering 25-45 N·m depending on pipe size, along with wire brushes for conductor surface preparation. No specialized crimping equipment is needed, reducing tooling requirements for contractors.
Yes, the pipe is designed for versatile use in both environments. Underground installations benefit from its corrosion resistance, while overhead applications utilize its lightweight properties and vibration resistance.
The bolted compression design maintains constant pressure on the conductor interface, preventing oxidation buildup. The anodized surface treatment and stainless steel hardware resist corrosion that could otherwise increase contact resistance.
The connecting pipe withstands short-circuit currents up to 31.5 kA for 1 second without mechanical failure or excessive resistance increase, meeting the fault current requirements of medium-voltage distribution systems.
