Low temperature cold bending tester for wires
PRODUCT DETAILS
Product Name: Low-Temperature Cold Bend Testing Machine for Wires and Cables
Model: JY-200A (Customizable)
Product Overview:
The Low-Temperature Cold Bend Testing Machine is designed to evaluate the flexibility and crack resistance of wires and cables under extreme cold conditions (-70℃ to +25℃). Compliant with GB/T 2951.14 and IEC 60811 standards, it simulates harsh environments for applications in new energy cables, automotive wiring harnesses, and military-grade cables, ensuring reliability in subzero temperatures.
Key Features
1.Ultra-Low Temperature Control
● Temperature range: -70℃ to +25℃ (±0.5℃ stability), achieving -70℃ in 30 minutes via liquid nitrogen cooling.
● Supports cyclic tests (up to 1,000 cycles) with alternating cold bending and ambient recovery.
2.Intelligent Bending System
● Servo-driven bending angles (0–180°), adjustable bending radius (R=5D–20D), and speed (1–30 cycles/min).
● High-precision torque sensors (±0.5%) detect insulation cracks or conductor fractures in real time.
3.Robust Construction
● 304 stainless steel chamber with double-layer insulated glass and German EBM low-temperature fans for 1,000+ hours of continuous operation at -70℃.
● Modular clamps accommodate single-core wires (Φ1mm) to multi-core cables (Φ50mm), with <5-minute setup.
4.Certified Data Output
● Generates CNAS/CMA-compliant reports with crack length, bending force curves, and 5MP HD video recording.
Applications
● New Energy: Charging pile cable testing (-40℃), solar cable flexibility validation.
● Automotive: Cold-start reliability tests for high-voltage wiring harnesses.
● Military/Aerospace: Arctic-grade aviation wire assessments.
● Certification Labs: UL 62/1581 compliance, export quality inspections.
Technical Specifications
● Temperature Range: -70℃ to +25℃ (extendable to -100℃)
● Bending Angle: 0–180° (motorized adjustment)
● Test Stations: 1–6 stations (optional)
● Sample Length: 300–1,000mm (customizable)
● Power Supply: AC380V 50Hz
