About 3M 11KV 3C*185SQMM INDOOR TERMINATION KIT

3M 11 kV, 3-core 185 sq mm indoor termination kit (cold-shrink / silicone style). This is a guideline the precise part number, dimensions and performance must be verified from the official 3M datasheet.

Purpose & Application

Used to terminate medium-voltage (MV) polymeric cables (XLPE, EPR, etc.) having 3 cores, cross-sectional area 185 sq mm, in indoor / enclosed installations (e.g., switchgear rooms, cable galleries, indoor junction boxes).
Provides insulation, electrical stress control (field grading), shielding / screen termination, void-free sealing, moisture protection, and mechanical transition to the termination hardware (lugs, busbars, connectors).
Designed with cold-shrink silicone / elastomeric construction so that no heat or flame is required during installation.

Typical Kit Contents & Components

A 185 sq mm kit of this nature would generally include:

Silicone rubber (pre-stretched, cold-shrink) termination body with integrated stress control / grading inserts (Hi-K or grading sleeves)
Breakout / trifurcation boots (cold-shrink boots) to branch the three cores downstream of the main body
Phase re-jacketing / insulating sleeves (to cover trimmed insulation ends)
Sealing / mastic / silicone grease / void filling compounds (for eliminating air gaps, sealing surfaces, moisture protection)
Constant-force springs / bonding springs (to provide reliable connection of the cables metallic shield / screen to ground)
Copper shield braid / foil / tapes for screen continuity and EMI shielding
Outer jacket / re-jacket sleeves or tubes for restoring the cable jacket where trimmed
Cleaning wipes, masking tape, installation tools, and full installation instructions

Electrical / Mechanical & Performance Specifications (Representative)

Below are expected / design-level properties (to be confirmed with actual datasheet):

Feature	Typical / Expected Value or Range
Voltage class	11 kV (often meant for 12 kV U systems)
Cable cross-section / size range	Centered on 185 sq mm; kit may cover a size band (for example 150240 sq mm or similar)
Insulation outer diameter (OD) range	Must match the actual OD of insulation + shield of the cable (this could be 2540 mm depending on design)
Stress control / grading	High-dielectric inserts or graded sleeves to smooth the electric field near shield cutback
Dielectric / insulation body	Silicone / elastomer, cold-shrink type, contracting to provide void-free insulation
Sealing & moisture protection	Mastic, silicone grease, tapes, and void filling compounds to avoid air pockets and moisture ingress
Shield / screen continuity	Bonding or constant-force springs, copper braid or screen tie elements to ground or earth the metallic screen
Creepage & clearance distances	Designed to satisfy creepage and clearance requirements per indoor medium-voltage termination standards
Impulse / switching stress	Capable of withstanding systems lightning / switching impulses as required for 11 kV systems
Operating / ambient temperature	Installation and service ambient range (e.g. 20 C to +50 C or similar)
Shelf life / storage	Many kits specify 23 years shelf life if stored under recommended conditions (e.g. 40 C to +50 C)
Standards / compliance	Should comply with relevant MV termination standards (e.g. IEC 60502-4, HD 629 / HD 620, or equivalent local standards)
