Poor Insulation Of Neutral Blocks? Reasons And Solutions Unveiled

Poor insulation of neutral blocks is a common problem in electrical connections, which may lead to safety hazards such as short circuits and leakage. The following will reveal its causes and solutions.

Cause analysis:

Insulation material issue: Aging, moisture or contamination of insulation materials can reduce their insulation performance. For example, long-term exposure to high temperatures and ultraviolet radiation can cause insulation materials to age easily; Damp environments or oil contamination can also cause a decrease in insulation performance.

Mechanical damage: Excessive crimping or external impact may cause the insulation layer to break, leading to poor insulation.

Design or manufacturing defects: The effective wall thickness of the insulator is too thin, the accuracy of the injection mold is insufficient, or the molding process is improper, all of which may affect the insulation effect.

Solution:

Replace insulation materials: Choose insulation materials with stronger weather resistance, such as silicone, flame-retardant PC, etc., to improve insulation performance.

Strengthen sealing protection: In humid environments, use waterproof terminals or sealing glue to prevent moisture and pollutants from entering.

Standard operation: During crimping, avoid crushing the insulation layer, keep the terminals clean, and prevent dust and solder from adhering.

Regular inspection and maintenance: Regularly inspect the neutral blocks to promptly identify and address insulation issues. For aging insulation materials, they should be replaced in a timely manner.

Optimize design and manufacturing processes: Improve the accuracy of injection molds and the level of molding processes, ensure that the effective wall thickness of insulators meets requirements, and improve insulation performance.
