CoralGreenE® is a global VPI system where Coral delivers the unimpregnated insulated coils or bars.

• CoralGreenE® is with insulation system that will be global impregnated with Epoxy anhydride

After completing the winding, the complete stator needs to be processed for VPI and Oven curing process.

At customer’s request we can fully impregnate motors or generators in our factories.

Ideally used for low to medium voltage motors and generators.

Advantages and special features:

• The coils can be easily installed in the stator core.
• The same main wall insulation tapes can be used for complete coils (Homogeneous insulation).
• It has good insulation resistance.

Construction of insulation Materials

• Materials used as per customer specifications and depending on the exact system requirements

Conductor covering :

• Enamel with Dalgass
• Enamel with Fiberglass
• Enamel with Mica
• Kapton wires
• Corona resistant Kapton

Mica tape and subsequent materials:

• Stack consolidation tape
• Mica tape with accelerator
• Mica tape without accelerator
• Kapton mica tape
• Corona shield tape
• Stress grading tape
• Finishing tape

Standards used for the insulation scheme

Coral®GreenE™ meets all international standards, IEC, IEEE and EASA, and customer standards

Standard and special testing alternatives

• Interturn test (Inhouse made device to check the interturn failure)
• Coil resistance measurement
• IR test IEEE 43:2000
• AC HV Test IS 4722:2001 or DC HV test (As per requirement)
• Surge comparison test – IEEE 522:2004
