There are a lot of electrical insulation laminated board sheet manufacturers, but how to choose insulation sheet for distribution box?

Generally, we will consider the voltage when choosing the insulation board of distribution box. We can take samples for testing. Voltage resistance test: 25KV (effective value), keep for 1min, no breakdown phenomenon; The breakdown voltage test is ≥35KV (effective value), and this is basically achieved. If higher requirements are required, further tests should be conducted. But if you have a certain value for this, you can ask the manufacturer to customize.

For small distribution boxes with low voltage, FR-4 epoxy resin fiberglass laminate sheet material may be used. For higher requirements, you can use FR4 insulation board. You can consult Henan Zhongtian Electrical Equipment Group (ZTelec Group) for details. Our company mainly produces and processes all kinds of insulating sheets, including epoxy fiberglass cloth laminated sheet, phenolic bakelite hylam sheet laminate board, FR4 fiberglass board, GPO3 insulating sheet, nylon board, SMC insulating board, advanced engineering plastics, etc.
