Ang carrying capacity sa bare conductor
Ania nga tool mokompyuta ang pinakamataas nga continuous current-carrying capacity sa mineral-insulated bare conductors nga may rating nga 750V, batasan sa Tables B.52.6 hangtod B.52.9 sa IEC 60364-5-52. Gi-suportahan kini sa copper o aluminum conductors sa uban nga installation conditions ug environmental corrections.
Mga Input Parameters
Pamaagi sa Installation: Batasan sa IEC 60364-5-52 (Table A.52.3), sama sa open air, buried, in conduit, etc. Pahinumdum: Wala tanang mga pamaagi anaa sa regulations sa bawat nasud.
Conductor Material: Copper (Cu) o Aluminum (Al), na nakaapekto sa resistivity ug thermal performance
Type:
PVC-covered o bare exposed to touch (metallic sheath temperature: 70°C)
Bare not exposed to touch and not in contact with combustible material (metallic sheath temperature: 105°C)
Wire Size (mm²): Cross-sectional area sa conductor
Phase Conductors in Parallel: Mga identical conductors mahimo mosugyot sa parallel; maximum permissible current mao ang sum sa individual core ratings
Ambient Temperature: Temperature sa surrounding medium kung wala nag-load:
Air temperature correction factor: IEC 60364-5-52 Table B.52.14
Ground temperature correction factor: IEC 60364-5-52 Table B.52.15
Soil thermal resistivity correction: IEC 60364-5-52 Table B.52.16
Circuits in the Same Conduit: Number of circuits inside one duct powering different loads (e.g., 2 lines for 2 motors). Reduction factors from IEC 60364-5-52 Table B.52.17 apply.
Mga Output Results
Pinakamataas nga continuous current (A)
Corrected value for ambient temperature
Reduction factor for multiple circuits
Reference Standards: IEC 60364-5-52, Tables B.52.6–B.52.9
Gidisenyo para sa mga electrical engineers ug designers aron mapili ang appropriate bare conductors para sa high-voltage o industrial power distribution systems, asegurando ang safe ug reliable operation.
