General
The 3M ™5815 Series Modular Splicing System is a fully shielded 600 Amp parable connector system which meets the requirements of ANSI/IEEE Standard 386 – "Separable Insulated Connector Systems." The modular kits are available for splicing, dead-ending and connecting to deadfront apparatus such as transformers, switches and
switchgear equipped with 600 Amp bushings. The system has the capability for future modification by simply adding or removing modular components.By combining kits, the system can accommodate 3-way, 4-way, parallel feed, etc. connections in various tap splicing configurations.
The modular kits are designed for u on 5, 8, 15 and 25 kV rated industrial shielded power cables. Kit instructions describe installations for tape shield,wire shield, UniShield ®‚ and jacketed concentric neutral types of solid dielectric cables with extruded mi-conductive insulation shields. A capacitive test point on the insulating plug provides a safe means of testing the circuit without disturbing the bolted connection. The completed installation is fully
shielded to provide a complete deadfront connection which is suitable for operation in submerged or direct burial locations.

Table 3Accessory
5815-B Series Adapter Kits adapt the splicing kit tee modules to specific cable sizes. The adapter kits include silicone lubricant.A T-Wrench accessory tool is available for u with kits containing Connecting Plug(s), such as the 5815-S and 5815-T Modular Splicing Kits.1.3
Product Features
The modular Splicing System features include:•Modular Design -allows custom tailoring for various splicing functions and configurations,such as multiple taps, ctionalizing, dead-ending, adding-on, etc.
•Bolt-together Components - allows dead-break disconnecting and reu of the connecting components (connecting plug, dead-end plug,connecting stud, etc.).
•Molded Conductive Outer Jacket -provides for a fully shielded dead-front connection which meets the requirements of IEEE Standard 592 –"Expod Semi-conducting Shields on High-V oltage Cable Joints and Separable Insulated Connectors."
•Kit Packaging -designed for industrial u, the kits simplify the lection, ordering and stocking of appropriate system components.
•Shield Adapter Kits -cold shrink design for simple shield rejacketing. Kits provide all of the components necessary for adapting the parable connector to specific cable sizes and shielding types of common industrial power cables.
•Voltage Test Point -the dead-end plug provides a high impedance test point for safely checking the de-energized status of the circuit.
2.0Applications
For connecting 5, 8, 15 and 25 kV shielded power cables to 600 Amp dead-front, dead break installations:
•For splicing – 2-way, 3-way and multiple taps •For adding-on •For dead-ending
•For 600 Amp equipment (apparatus) connections •For shielded solid dielectric (e.g. EPR and XLPE)cables with extruded mi-conductive insulation shield
•For power cable locations: Manhole, Vault,Cabinet, Junction Box, Cable Tray, Direct Burial •For submerged locations
•For ctionalizing cable systems
3.0Installation
A torque wrench and one-inch socket is ud to tighten the insulating plug through the compression connector within the tee-module body, onto a de-energized 600 A bushing interface. A 3M ™5815-TW T-wrench is ud for installing a connecting plug into a Tee Module, for kits containing a
connecting plug (e.g. the 5815-S and 5815-T). Refer to the 5815 Series kit instructions for details.

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 ud 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 tho available from other major manufacturers.
4.0Data
The 3M 5815 Series Modular Splicing System can be ud on shielded power cables with a rated operating temperature of 90°C. and an emergency overload rating of 130°C. Connections made with the kits are rated for V oltages up to 25 kV and meet the requirements of ANSI/IEEE 386 for 600Amp 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 V oltage Level - 19 kV
Tests conducted in accordance with manufacturer ’s requirements:
•Physical Inspection •Periodic Disction
•Periodic Fluoroscopic Analysis 4.2
Grounding
Grounding of the Tee Module and cable metallic shield is performed using the Ground Braid
Asmbly provided with each 5815-B Series Adapter Kit. The asmbly 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 21,600circular mils Ground Braid can be plotted as follows:
