Turkey's electricity transmission network is one of the fastest growing grids in Europe, with new high-voltage lines connecting renewable energy regions to major demand centers across Anatolia. As the grid expands, the long-term performance of composite and polymeric insulators has become a critical concern for utilities such as TEIAS and regional distribution companies. Without rigorous aging assessment, insulators exposed to harsh weather can degrade prematurely, leading to tracking, erosion and flashover failures that interrupt supply to millions of consumers.
The IEC 62730-2024 standard defines a 5000-hour multiple stress test that simulates the real environmental conditions polymeric insulators face over decades of service. It combines solar simulation, ultraviolet radiation and salt spray cycles in a single chamber, reproducing the combined aging mechanisms that accelerate insulator deterioration. This accelerated test is widely regarded as the most comprehensive way to predict field performance before mass deployment.
Single-stress tests cannot reveal the combined degradation that occurs in the field. A polymeric insulator may pass a standalone salt spray test or a UV test yet still fail prematurely when both stresses act together over time. The IEC 62730 multi-stress chamber closes this gap by applying the stresses in a controlled, repeatable cycle.
Daxian's IEC 62730 multi-stress test machine delivers uninterrupted 5000-hour aging with dual xenon arc and UV fluorescent light sources, automatic salt spray cycling and PLC touch-screen control. The chamber accommodates insulators with 500mm to 800mm creepage distance, matching the exact specimen requirements of the standard.

For Turkish utilities and insulator suppliers, an in-house IEC 62730 test capability shortens qualification cycles, builds confidence with international buyers and supports compliance with TSE-aligned IEC requirements. It is an essential tool for any organization serious about long-term grid reliability in a demanding and rapidly growing market.
Beyond compliance, regular multi-stress testing supports condition-based maintenance and supplier benchmarking. Utilities that maintain continuous aging data can anticipate when insulator populations approach end-of-life and schedule proactive replacement rather than reacting to failures after they occur, protecting both network availability and public safety.
