Al-Al Parallel Groove Clamp JB Overview
This Al-Al Parallel Groove Clamp JB guarantees excellent electrical continuity without diminishing the native capacity of the transmission line.
- Constructed with high-grade Aluminium Alloy for both the upper and lower jaws.
- Utilizes robust Grade 8.8 fasteners to maintain a consistent clamping force.
- Maintains an electrical resistance strictly ≤ 1.1 times the equivalent length of the reference conductor.
- Ensures the joint’s surface temperature rise remains equal to or below that of the reference conductor.
Al-Al Parallel Groove Clamp JB Features
Utilizing the Al-Al Parallel Groove Clamp JB streamlines utility construction with highly flexible direct-factory terms:
- Oxidation Control: Pre-applied with an oxide-inhibiting compound to effectively minimize metal oxidation over time.
- Mechanical Integrity: Provides a reliable failure slip load equal to 10% of the reference conductor’s calculative tensile strength.
- Hardware Options: Available with either hot-dip galvanized or stainless steel fasteners to suit diverse environmental conditions.
- Order Flexibility: Zero Minimum Order Quantity (MOQ) on initial purchases, free samples provided (buyer covers freight), and full ISO (9001, 14001, 18001) quality control.
Al-Al Parallel Groove Clamp JB Applications
Designed exclusively for non-tension bridging, the Al-Al Parallel Groove Clamp JB is an essential utility grid fitting. It is strictly used for:
- Creating secure parallel connections in pure Aluminium to Aluminium (Al-Al) overhead networks.
- Linking steel-reinforced Aluminium conductors or non-linear pole jumpers safely.
- Fulfilling standard hardware requirements for expansive low and medium-voltage (LV and MV) EPC projects.
