Macey 25kV High Voltage Coupling Systems

Electrical test data:

• AC withstand: 50kV for 1 minute; 40kV for 6 hours
• Short circuit: 25kA for 0.3 seconds (3 tests, two 10-minute intervals)
• Basic impulse level: 125kV B.I.L.
• Earth through fault: 8kA for 0.2 seconds (3 tests, two 10-minute intervals)
• Heat rise: 700 amps after 100 cycle contact pre-conditions at 45k over ambient and no more than 10k over the conductor

Environmental ratings:

• IP66/67 testing to IEC 60529

• No special installation tools needed
• Smaller footprint and reduced weight versus the competition
• Intermatable with other manufacturers' couplers
• Accommodates a wide range of cable types with entrance fittings, including fiber optic
• Retained bolting system
• Low insertion force/high current design
• Total air displacement – no potting of rear body termination point
• Slip-on stress cone termination module with compression type wire stems eliminates heat or cold shrinking (Tyco) sleeves
• Fully shielded phase compartment eliminates phase-to-phase faults
• Louvered contact banding for: higher current capacity; lower contact pressure; improved short circuit performance
• No altitude de-rating required
• Slip-on stress cone termination module eliminates strain on contact restraining clip
• Lockout/tagout feature

• Housing – aluminum
• Adapter – aluminum
• Insulated end cover – aluminum
• Cast protection cover – aluminum
• Contacts and wire stems – silver-plated copper
• Hardware – 316 stainless steel
