In the field of wires and cables, polyolefin insulated wires are widely used in various industries such as power, communications, and construction due to their excellent electrical properties, chemical corrosion resistance, and mechanical strength. However, wire aging is a key factor affecting its safety and service life. Therefore, understanding the aging test standards for polyolefin insulated wires is crucial for selecting and using high-quality wires.
I. Core Standards for Aging Testing
Aging tests for polyolefin insulated wires are primarily based on relevant international and domestic standards, such as the GB/T 2951 series and IEC 60227 series standards. These standards specify in detail the test methods and evaluation indicators for wires under different environmental conditions, including thermal aging, light aging, and damp heat aging. For example, thermal aging tests simulate long-term use of wires in high-temperature environments to assess the degradation of their insulation performance; light aging tests use artificial light sources to simulate sunlight exposure and examine the weather resistance of the wire insulation layer.
II. Key Indicators for Aging Testing
In aging tests, insulation resistance, dielectric strength, and elongation at break are important indicators for assessing the degree of aging of wires. A decrease in insulation resistance may indicate that the insulation layer is damp or aged; a decrease in dielectric strength means a reduction in the safety of the wire under high-voltage environments; and a decrease in elongation at break reflects the deterioration of the mechanical properties of the insulation layer.
