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.
