Principer för val av tråd och arrangemang av explosionssäker elektrisk utrustning

1. Inuti utrustningen, anslutningar mellan olika komponenter måste använda kopparkärna isolerade ledningar, som kan vara antingen standardkablar eller kablar. This wiring’s insulation needs to adhere to the equipment’s rated voltage criteria, och dess kapacitet för strömflöde och värmealstring måste överensstämma med etablerade standarder, 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. dock, it’s imperative that egensäker 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. Standard, unshielded high-frequency wires should not be installed parallel to other wires.

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