CABLING PROTECTION - Coggle Diagram
CABLING PROTECTION
METHOD OF CABLE SIZING
Determine the minimum cable size based on
inrush current SC
Determine the minimum cable size based on
short circuit temperature rise SD
Determine the minimum cable size based on
voltage drop SB
Select the cable based on the largest of the sizes calculated in steps above S=MAX(SA,SB,SC,SD)
Determine the minimum cable size based on
current rating
.
Cross-linked polyethylene (XLPE)
Changes the molecular structure of the polymer chains so that more tightly bound together
Chemical crosslinking involves the addition of chemicals
Thermoset insulation material
Ethylene Propylene Rubber (EPR)
Wide thermal range typically in the region of -55°C to 150°C
Resistant to a wide range of other chemicals including many acids, alkalis and organic solvents.
Insulation material for electric cables due to its high dielectric strength
EPR insulation is suitable for many higher voltage applications
Thermoset insulation material
Polyvinyl chloride (PVC)
Suitable for applications where the cables may be exposed to high or low temperatures
Frequently used owing to its good insulating properties
Thermoplastic polymer
