AC90 Wire Overview
What is AC90 Wire?
AC90 wire is a high-quality, insulated electrical cable designed for alternating current (AC) applications. The "AC" in AC90 denotes its suitability for AC circuits, while "90" refers to its heat resistance rating-meaning the wire can safely operate in environments up to 90°C without degradation.
Constructed typically with copper conductors and durable PVC insulation, AC90 wire is flexible, highly conductive, and resistant to corrosion, making it an ideal choice for both indoor and outdoor installations.
Key Technical Features
- Voltage Rating: Typically up to 450/750V, depending on specifications.
- Temperature Rating: Up to 90°C.
- Conductor Material: High-purity copper for excellent electrical conductivity.
- Insulation Material: Flame-retardant PVC for safety and durability.
- Standards Compliance: Meets national and international electrical standards.
Advantages of AC90 Wire
- Safety: High insulation quality reduces fire and electric shock risks.
- Durability: Resistant to moisture, heat, and mechanical stress.
- Versatility: Suitable for residential, commercial, and industrial applications.
- Ease of Installation: Flexible design simplifies wiring in confined spaces.
