When it comes to arcade machine wiring, proper insulation is crucial for safety, durability, and optimal performance. The most common types of insulation materials used include:

1. PVC (Polyvinyl Chloride) Insulation: Widely used due to its affordability, flexibility, and resistance to moisture and abrasion. PVC-coated wires are ideal for general-purpose wiring in arcade cabinets.

2. Fiberglass Insulation: Known for its high heat resistance, fiberglass is often used in areas where wires may be exposed to elevated temperatures, such as near power supplies or lighting systems.

3. Silicone Insulation: Offers excellent thermal stability and flexibility, making it suitable for high-temperature environments or where frequent movement of wires occurs.

4. Rubber Insulation: Provides good elasticity and resistance to wear, though it’s less common in modern arcade machines due to the prevalence of PVC and silicone.

5. Teflon (PTFE) Insulation: Used in premium applications for its superior heat resistance and low friction, though it’s more expensive than other options.

Choosing the right insulation depends on factors like temperature exposure, mechanical stress, and budget. Proper insulation ensures longevity and reduces the risk of electrical hazards in arcade machines.
