To solve the common aging defects of conventional wires, our company carries out targeted research on anti-aging technologies for wires. Optimizing anti-aging performance can effectively improve the operational reliability of cables, reduce later maintenance costs, and meet the higher requirements of customers for product durability and safety. It also helps our products adapt to more harsh application environments and enhance overall market competitiveness.
1.2 Existing Problems Caused by Wire Aging
Traditional wires are prone to multiple aging failures in long-term use. The insulation layer will gradually age and deteriorate, resulting in decreased insulation resistance and poor electrical protection ability. The outer sheath is easy to crack, embrittle and deform under the combined effect of external forces and environmental factors. In addition, aging will cause deviation of core electrical parameters, loose internal structure, and even wire breakage and short circuit in severe cases, which seriously affects the stable operation of the whole power system.
1.3 Solution Objectives and Application Scope

It covers low-voltage, medium-voltage conventional power wires, control wires and special environmental cables independently developed and produced by our company.
2. Analysis of Wire Aging Mechanism
2.1 Main Aging Inducing Factors
2.1.1 Environmental Factors
Temperature is one of the key factors accelerating aging. Long-term high temperature will accelerate the molecular chain decomposition of insulating and sheath materials; extreme low temperature will cause material hardening and brittleness. Humid air and rainwater will penetrate into the cable interior, triggering damp aging and electrochemical corrosion. Long-term exposure to ultraviolet radiation outdoors will destroy the surface structure of polymer materials. Meanwhile, oxygen in the air will produce oxidation reaction with cable materials, continuously promoting material aging.
2.1.2 Operational Factors
During operation, long-term overload current will generate continuous heat inside the wire and aggravate thermal aging. Frequent mechanical friction, stretching, bending and equipment vibration will damage the cable structure and accelerate the fatigue aging of materials. Repeated switching and instantaneous current impact will also affect the internal stability of wires.
2.1.3 Chemical Corrosion Factors
When cables are laid in chemical workshops, near pipelines of acid, alkali and salt substances, or in polluted soil, corrosive media will erode the outer sheath and penetrate inward, resulting in chemical aging and corrosion damage of wires.
2.2 Typical Manifestations of Aging Failure
1.Declined insulation performance: Insulation layer ages and fails, leakage current increases, and insulation protection function decreases.
2.Material damage: The sheath and insulation layer appear cracking, peeling, embrittlement, swelling and permanent deformation.
3.Mechanical performance degradation: The tensile strength, wear resistance and bending resistance of wires are significantly reduced.
4.Electrical parameter drift: Resistance, voltage resistance and other indicators deviate from the standard, affecting normal power transmission.
5.Structural failure: Internal conductor loosening, layer separation, and even short circuit and open circuit faults.
