TianYuan TY8000B Horizontal Electronic Tensile Testing Machine

Overview

The TianYuan TY8000B Horizontal Electronic Tensile Testing Machine is a precision-engineered mechanical testing system designed for high-reliability static tensile and mechanical performance evaluation of power line hardware—including pre-twisted fittings, optical cable accessories, structural components, raw materials, incoming inspection samples, and finished products. Its horizontal frame architecture—constructed using submerged arc welding and post-weld stress-relieved quenched-and-tempered steel—ensures dimensional stability under sustained loading conditions. Unlike vertical configurations, the horizontal layout accommodates extended test specimens (e.g., long-span conductors, tension clamps, or composite insulator assemblies) while minimizing gravitational bending moments during loading. The machine operates on a servo-controlled electromechanical actuation principle, delivering repeatable force application with closed-loop feedback from a calibrated 100 kN load cell and high-resolution linear displacement transducers. It complies with fundamental mechanical testing principles defined in ISO 7500-1 (static calibration of uniaxial testing machines), ASTM E4 (load verification), and ASTM E8/E8M (tensile testing of metallic materials), supporting traceable metrology through NMI-certified sensor and controller calibration.

Key Features

• Horizontal rigid frame with stress-relieved quenched-and-tempered structural steel, minimizing thermal and mechanical drift during prolonged tests.
• Floating jaw design with self-centering capability ensures axial alignment without inducing torsional or shear stresses on the specimen—critical for accurate failure mode analysis of asymmetric or threaded hardware.
• Dual-mode operation: fully programmable automatic testing (with user-defined load ramps, dwell periods, and break-point capture) and manual override for setup, pre-tensioning, or diagnostic checks.
• Load-hold functionality maintains applied force within ±1% fluctuation over user-specified durations—essential for creep assessment and proof-load verification per IEC 61238-1 and GB/T 2317.1.
• Vibration-dampened break detection system decelerates crosshead motion upon specimen rupture, reducing rebound-induced damage to both test article and gripping surfaces.
• Integrated overload, overtravel, and overforce protection circuits conform to EN 61000-6-2/6-4 EMC requirements and prevent mechanical shock transmission to drive train components.
• Modular load cell and displacement sensor architecture allows field removal and independent recalibration by accredited metrology laboratories—supporting ISO/IEC 17025-compliant quality systems.

Sample Compatibility & Compliance

The TY8000B accommodates specimens up to 1000 mm in total stroke length and 800 mm of effective tensile space (excluding fixture interfaces), with internal test zone dimensions of 1500 mm × 500 mm × 500 mm—enabling evaluation of full-scale power fittings, suspension clamps, armor rods, and multi-strand conductor assemblies. Standard wedge-action and serrated flat grips are included; custom hydraulic or pneumatic fixtures can be integrated for specialized geometries. The system supports compliance testing per GB/T 2317 (mechanical and electrical tests on overhead line fittings), DL/T 758 (pre-twisted wire fittings), IEC 61238-1 (compression and wedge-type connectors), and ASTM F1043 (mechanical performance of guy strand anchors). All force and displacement measurements are traceable to national standards via factory calibration certificates issued by CNAS-accredited institutes.

Software & Data Management

The machine operates with embedded real-time control firmware and optional PC-based testing software featuring intuitive graphical workflow configuration. Users define test profiles—including ramp rates, hold durations, stop conditions (e.g., yield point, maximum elongation, or fracture), and data sampling intervals (down to 100 Hz). Raw force-displacement curves, time-stamped event logs, and statistical summaries (mean, SD, CV%) are exportable in CSV, PDF, and XML formats. Audit trails record operator ID, parameter changes, calibration events, and test execution history—meeting GLP/GMP documentation requirements and aligning with FDA 21 CFR Part 11 electronic record controls when configured with user authentication and digital signature modules.

Applications

• Mechanical qualification of pre-twisted suspension and vibration dampers per IEC 61400-23 and GB/T 19072.
• Proof-load and ultimate tensile strength verification of aluminum alloy and stainless steel power fittings used in 110 kV–1000 kV transmission infrastructure.
• Incoming material inspection of galvanized steel wire, ACSR conductors, and FRP cores against tensile modulus and elongation-at-break specifications.
• Research-grade characterization of interfacial bonding strength in hybrid composite-clamp systems under controlled strain rates.
• Long-term load retention testing for hardware subjected to environmental aging (e.g., salt fog + UV preconditioning followed by tensile hold).

FAQ

What standards does the TY8000B support for calibration and testing?
It adheres to ISO 7500-1 for machine verification, ASTM E4 for load cell calibration, and ASTM E8/E8M for metallic tensile procedures. Optional software modules support automated report generation compliant with GB, IEC, and ASTM templates.
Can the system perform creep or relaxation tests?
Yes—via programmable load-hold sequences with configurable duration and force tolerance bands, enabling time-dependent deformation analysis per ASTM D2990 or ISO 899-1.
Is remote diagnostics or firmware update capability available?
The embedded controller supports Ethernet-based remote monitoring and secure firmware updates through authenticated TLS-encrypted channels, subject to network configuration.
What is the recommended maintenance interval for the load cell and drive system?
Annual recalibration of the load cell and verification of crosshead speed accuracy are advised; lubrication of lead screws and inspection of grip jaw inserts should occur every 500 operational hours.
Does the machine meet electromagnetic compatibility (EMC) requirements for industrial laboratories?
Yes—it conforms to EN 61000-6-2 (immunity) and EN 61000-6-4 (emissions) for industrial environments, with CE marking valid for EU deployment.
