In cable-related industries, where standards require rigorous validation-such as ozone resistance, weathering, corrosion, mechanical stress, and low-temperature/UV testing-reliability and long-term durability are essential.
LIB's advanced environmental test chambers, including Ozone, Gas Corrosion, Xenon Arc, and Salt Spray systems, are purpose-built to simulate real-world stresses such as ozone attack, gas corrosion, light degradation, and salt fog exposure.
1. Ozone Test Chamber
LIB's Ozone Test Chamber simulates ozone-rich environments, providing precise control over ozone exposure to evaluate cable materials like rubber and elastomers. This chamber helps predict how cables will perform in real-world conditions, such as electrical insulation and automotive seals, by accelerating rubber aging and identifying potential degradation in ozone-prone environments.
Performance Features & Benefits to Cable Testing:
Ozone Concentration Control (1–1000 PPHM):
With a PID programmable controller, this chamber ensures precise control over ozone exposure, simulating different ozone levels. This allows customers to assess the potential for cracking, hardening, or surface degradation of cables used in environments with varying ozone concentrations.
Dynamic Sample Holder (360° Rotation, 1-10r/min):
The rotating holder ensures uniform stress distribution across samples, stretching them by 5%-35%. This feature mimics real-world stretching and movement, providing valuable insights into how cable materials will perform when subjected to mechanical stresses in their applications.
Comprehensive Climate Control (0–100°C, 30%–98% RH):
The chamber's temperature and humidity control allows for testing across a range of environmental conditions, helping customers evaluate cable durability and performance in different climates, whether hot and dry or cool and humid.
Safety Features (Activated Carbon Filters System):
The ozone exhaust system neutralizes harmful residual gases, ensuring safe operation and compliance with environmental safety standards. Customers can perform tests safely, knowing the environment remains hazard-free.
2. Gas Corrosion Test Chambers
LIB offers two chambers to test cable resistance against aggressive gases like sulfur dioxide and mixed gases, crucial for cables used in industrial, marine, and polluted environments.
SO₂ Noxious Gas Test Chamber (Single Gas)
Sulfur Dioxide Exposure (25±5 ppm):
This chamber exposes samples to pure sulfur dioxide, replicating environments like industrial plants. It allows customers to evaluate how cables react to sulfur dioxide, which can cause degradation in certain materials over time.
Real-time Parameter Monitoring (Temperature, Humidity, Gas Concentration):
With precise sensors and a PID controller, customers can track temperature, humidity, and SO₂ concentration, ensuring that each test is accurate and consistent. This enables reliable predictions of how cables will perform when exposed to varying environmental conditions.
Safety Features (NaOH Solution Tank):
An automated NaOH solution neutralizes exhaust gases, preventing harmful emissions. This ensures customers can carry out tests safely and in compliance with environmental regulations.
Mixed Flowing Gas Corrosion Test Chamber
Multi-Gas Exposure (H₂S, NO₂, Cl₂, SO₂):
This chamber simulates real-world industrial environments, exposing cables to multiple aggressive gases. Customers can assess how cables perform under combined gas stress, which is essential for ensuring cable longevity in complex environments like factories and polluted industrial zones.
Advanced Structural Design (Double-layer Sealing, Stainless Steel Interior):
The robust construction prevents cross-contamination between gases and ensures long-term durability, offering customers a reliable platform to test cable materials under mixed gas conditions.
Precise Environmental Control (15–80°C, 30%–98% RH):
With controlled temperature and humidity, customers can simulate real-world conditions, testing how cables respond to fluctuating environmental factors while exposed to corrosive gases.
3. Xenon Arc Test Chamber & UV Weathering Test Chamber
LIB's Xenon Arc Test Chamber and UV Weathering Test Chamber simulate outdoor environmental conditions such as UV radiation, extreme temperatures, and humidity to evaluate cable performance and aging in real-world applications.
Xenon Arc Test Chamber
Full Solar Spectrum Simulation (280–800 nm):
The xenon lamp replicates the full spectrum of sunlight, including UV, visible, and infrared radiation. This allows customers to simulate the impact of sunlight on cables used in outdoor environments, assessing how cables react to UV-induced degradation and photo-oxidation.
Rotating Sample Holder (42 Specimens, customizable):
Ensures even irradiation across all specimens, enabling customers to assess how the entire cable surface degrades under prolonged exposure to sunlight. The rotating holder guarantees that the test results are consistent and reliable.
Low-Temperature Testing (-40°C Option):
The chamber can simulate freezing conditions, enabling customers to test cable flexibility and durability in cold climates. This is essential for cables used in harsh weather conditions or high-altitude environments where low temperatures are common.
UV Weathering Test Chamber
UV-Induced Aging Simulation (290–400 nm):
The UV lamps focus on the wavelengths that cause aging, helping customers evaluate how cables will degrade when exposed to UV radiation, whether indoors or outdoors.
Precise Irradiance Control (0.15–1 W/m²):
Adjustable irradiance levels allow customers to simulate different UV intensities, ensuring that the test results match the specific conditions the cables will face in real-world applications.
Stable Humidity Control (≥95% RH):
The chamber maintains high humidity to simulate environments where cables are exposed to both UV radiation and moisture, helping customers test how moisture combined with UV radiation affects the durability of cables.
4. Salt Spray & Cyclic Salt Corrosion Test Chambers
LIB's Salt Spray and Cyclic Salt Corrosion Test Chambers are designed to simulate the corrosive effects of salt-laden air on cables, crucial for applications in coastal, offshore, or industrial environments.
Basic Salt Spray Test Chamber
Uniform Salt Fog Generation: The chamber generates uniform salt fog(Salt spray deposition of 1-2 ml/80 cm2), allowing customers to test cables for corrosion caused by salt exposure. This is essential for cables used in marine environments, where salt fog can accelerate corrosion of metal and polymer components.
Stable Temperature and Humidity Control: The chamber maintains consistent conditions, ensuring that each test is performed under repeatable environmental factors. This enables customers to obtain reliable results and predict how cables will perform in marine and industrial environments.
Cyclic Salt Corrosion Test Chamber
Salt Spray, Drying, and Wetting Phases: The chamber cycles between salt spray and drying phases, simulating the natural fluctuation between wet and dry conditions that cables may encounter in coastal and industrial environments.
Wide Temperature and Humidity Control (10–90°C, 30%-98% RH): The ability to control both temperature and humidity allows customers to simulate a variety of real-world conditions, ensuring that cables are tested for long-term durability in varying climates.
Water Recirculation System: The external salt tank and water recirculation system reduce water consumption while maintaining consistent salt spray conditions, offering an environmentally-friendly and cost-effective solution for testing.
