In daily life and industrial applications, AC90 cables are widely used in buildings, factories, and outdoor wiring. However, many users may not realize a critical issue: what happens to cables when they are exposed to sunlight for a long time?
Imagine cables on a construction site enduring the scorching sun day after day, or outdoor wiring exposed to UV rays and heat year-round. At first glance, they may seem intact, but their internal structure may already be compromised.
Without timely prevention and high-quality cables, this can lead to electrical failures, increased maintenance costs, or even serious safety hazards.
This article will explain what happens to AC90 cables under sunlight, and provide practical solutions to extend cable life and ensure project safety.
What Is AC90 Cable?
AC90 cable is a common low-voltage power transmission cable widely used in industrial, construction, and outdoor power systems. Key features include:
- Material and Construction: AC90 cables use high-quality copper conductors with PVC (polyvinyl chloride) insulation and sheathing, offering excellent insulation and corrosion resistance.
- Applications: Outdoor power transmission, building electrical distribution, factory equipment power supply.
- Performance Advantages: Wear-resistant, tensile-resistant, and chemical-resistant, suitable for a variety of challenging environments.
Understanding the material and application of a cable is essential. AC90 cables are chosen in many projects for their stability and durability.
The Impact of Sunlight on Cables
Even though AC90 cables are durable, long-term exposure to sunlight can pose several risks:
UV Aging
- UV rays in sunlight gradually degrade the PVC sheath, making it brittle and prone to cracking.
- Over time, insulation performance may decline, increasing the risk of leakage or short circuits.
High Temperature & Thermal Expansion
- Direct sunlight raises cable surface temperature, and repeated expansion and contraction can damage the internal structure.
Increased Safety Hazards
- Aged cables are more prone to conductor breakage and insulation failure, which can cause electrical faults or even fire hazards.
Industry tests show that AC90 cables exposed to sunlight for extended periods may have a 30%-50% shorter service life compared to cables in normal environments.
Signs of Long-Term Sun Exposure
Users can identify cable aging through the following indicators:
Appearance Changes
- The sheath color fades and surface cracks or roughness appear.
- PVC sheath may show chalking or flaking.
Reduced Mechanical Performance
-
Feels hard or brittle, making handling and installation more difficult.
Decline in Electrical Performance
-
Oxidation on the conductor surface can reduce conductivity, affecting stable power transmission.
Regular inspection allows early detection of potential problems, preventing work delays or accidents caused by cable aging.
