防爆電氣設備嘅電線選擇同佈置原則

1. 設備內部, 各種組件之間嘅連接必須使用銅芯絕緣佈線, 可以係標準電線或電纜. This wiring’s insulation needs to adhere to the equipment’s rated voltage criteria, 其電流和熱量產生能力必須與既定標準保持一致, similar to the requirements for intrinsically safe electrical devices.

2. Wires within the equipment must be routed to avoid any contact with parts that are either high-temperature or mobile.

3. Internal wiring should be tidily arranged and securely bundled. 然而, it’s imperative that 本質安全 wiring is not bundled together with other types of wires. ‘Tidily arranged’ implies that each wire in the bundle should avoid crossing or tangling with others.

4. 標準, unshielded high-frequency wires should not be installed parallel to other wires.

5. Intermediate connections or joints are not permissible on internal wiring.
