3.1 Interchangeability
All 3M 5815 Series 600 A Deadbreak Connectors
conform to the electrical, mechanical and
dimensional requirements of ANSI/IEEE Standard
386. The connectors can be used on any comparably
rated bushing interface that also meets the
requirements of this standard. In addition, all
connecting plugs, dead-end plugs, compression
connectors and connecting studs are designed to be
interchangeable with those available from other
major manufacturers.
4.0 Data
The 3M 5815 Series Modular Splicing System can
be used on shielded power cables with a rated
operating temperature of 90° C. and an emergency
overload rating of 130° C. Connections made with
these kits are rated for Voltages up to 25 kV and
meet the requirements of ANSI/IEEE 386 for 600
Amp dead-break interfaces.
4.1 Production tests
Test are conducted in accordance with ANSI/IEEE
Standard 386:
• Ac 60 Hz 1 Minute Withstand - 40 kV
• Minimum Corona Voltage Level - 19 kV
Tests conducted in accordance with manufacturer’s
requirements:
• Physical Inspection
• Periodic Dissection
• Periodic Fluoroscopic Analysis
4.2 Grounding
Grounding of the Tee Module and cable metallic
shield is performed using the Ground Braid
Assembly provided with each 5815-B Series Adapter
Kit. The assembly is an integrated design which
incorporates both a ground braid for grounding the
cable metallic shielding and a ground lead (bleeder
wire) for connecting to the Tee Module grounding
tabs. A solderless connection is made to the cable
metallic shield using a constant force spring.
• Ground Braid: 21,600 circular mils, tinned
copper (7 AWG copper equivalent)
• Ground Lead (bleeder wire): 14 AWG solid,
tinned copper
The typical fault current performance for the 21,600
circular mils Ground Braid can be plotted as follows:
