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
