Why Do Puncture Clamps Need To Undergo Three 14-day Cycle Tests In Sulfur Dioxide And Salt Spray Environments?

The cable piercing connector equipment used in power distribution is frequently exposed to environments containing corrosive gases and sea salt mist. The combined effects of sulfur dioxide and salt mist trigger electrochemical reactions on metal surfaces, salt deposition, and microcrack propagation. Because these environments accelerate the aging of cable ipc connector materials and damage to connector interfaces, the company decided to conduct three 14-day cyclic tests to simulate the long-term exposure scenario of electrical piercing connector.

After one 14-day immersion or exposure, insulation connector surfaces may already show initial corrosion products or interface deterioration. Repeating the 14-day cyclic test three times allows for the gradual accumulation of the effects of chemical corrosion, alternating wet and hot conditions, and salt redeposition.
