Cable and Wire Tensile Strength Testing Machine | High Precision Pull Force Tester for Electrical Cables & Wires – UL 817 Standards Compliant
Product Description
The Cable and Wire Pull Strength Tester is a high-precision device designed to evaluate the mechanical strength of plugs, connectors, and cables. By simulating real-world scenarios such as sudden pulls, rotations, and lifting loads, it ensures that wires, cables, and their connected components remain securely connected under stress, effectively preventing accidental disconnection. Widely used in plug production lines, quality inspection laboratories, and power cable manufacturing, it is an ideal testing solution for ensuring the mechanical safety of electrical products.
International Reference Standards
- UL 817: Requirements for sudden pull strength, rotational testing, and current load testing of plug and cord assemblies.
- (UL817 No. 99.1-99.2 "Turning test", No. 100.1-100.3 "Sheath retention test")
- ANSI/EIA 364-38B: Specifies a test procedure for the axial pull of cable clamps on electrical connectors to evaluate their tensile retention capabilities.
- IEC 60794-1-311:2024: Test method for tensile strength and elongation of optical fiber cable components (Method G11A).
- EN 50289-3-16: Mechanical test standard for telecommunication cables, covering laboratory methods for determining the tensile properties of cables.
Test Objects and Inspection Items
Applicable Objects
- Power plugs, connector terminals
- Household appliance cables (e.g., rice cooker, washing machine power cords)
- Communication cables (network cables, fiber optic cables)
- Automotive charging station cables (QC3.0 fast charging device cables)
Testable Items
- Sudden tensile strength: Tests the connection strength between the plug and the conductor under simulated sudden tensile forces.
- Rotational fatigue: Tests the cable's durability under torsion.
- Current load performance: Verifies connection stability after applying current (e.g., 30A/12V).
- Elongation and breaking strength: Analyzes the mechanical behavior of the cable as it stretches and deforms to fracture.
