About 3M 11KV 3C*35SQMM INDOOR TERMINATION KIT

3M 11 kV, 3-core, 35 sq mm indoor termination kit (cold-shrink / silicone type) note: exact part number or variant may vary, so these are representative characteristics based on 3Ms MV termination product line:

Purpose / Application

Used to terminate medium-voltage (MV) cables (3-core) rated 11 kV (or similar class) in indoor / enclosed / switchgear / cable box installations.
Provides insulation, stress control, sealing, and shielding termination from the cable to the connection point.
Designed for polymeric insulated cables (e.g. XLPE or EPR) with shield (tape / wire / UniShield) and possibly armour / screen continuity.
Should comply with applicable standards like IEC 60502, HD 620, etc.

Key Parts / Components (typical kit content)

A termination kit generally contains:

Component	Function / Purpose
Silicone rubber insulator / outer tube	The main dielectric body that covers the termination region
High dielectric-constant (Hi-K) stress control tubes / sleeves	To shape the electric field on the shield cutback and reduce stress concentrations
Conformable or semi-conductive stress control compound / mastic	To fill voids and ensure a smooth interface, avoid air gaps, and provide graded field
Sealing compounds / mastic / silicone grease	To ensure moisture ingress protection and seal interfaces
Cold-shrink (pre-stretched silicone) core or tubing	The body is supplied in expanded state and shrinks when inner core is removed (no heat required)
Breakout boots / cold-shrink boots (for cable triple leg breakout)	For splitting the three cores from the common termination body to individual phase leads
Armour continuity components / earth strap / braid / bonding springs	To maintain continuity of metallic screen / armour, connect to ground or shield as needed
Re-jacketing sleeves / tubes	To re-cover portions of the cable jacket if removed or trimmed during preparation
Accessories (cleaning wipes, installation tools, masking tape, instruction sheet)	To help with installation, cleaning of cable insulation surface, etc.

Typical Electrical / Mechanical Properties & Ratings

Below are typical / expected attributes (the actual values depend on the specific variant chosen):

Parameter	Typical Value / Range
Voltage class	11 kV (some kits may go up to 12 kV)
Acceptable cable cross-section for 3-core	35 sq mm (but many kits can cover a range, e.g. 1695 sq mm or more)
Insulation outer diameter range	Depends on cable design; kit must accommodate the OD of cable insulation + shield
BIL / impulse withstand	The termination must meet impulse / lightning withstand levels as per standard (e.g. 95 kV BIL for many MV terminations)
Partial discharge / void-free sealing	The kit must seal without internal voids to avoid corona / PD onset
Dielectric / Stress grading	The stress control parts regulate the field to prevent excessive local stress
Temperature / environmental	Should be stable in service temperature range, humidity, indoor environment
Shelf life	Many kits have a shelf life (e.g. 3 years if stored properly)

For example, the 3M Cold Shrink QT-III series are designed for 5 to 35 kV and provide a void-free seal, stress control, and indoor suitability. 3M+33M Multimedia+33M Multimedia+3

Also, 3Ms datasheet for their 11 kV, 3-core indoor cold-shrink termination class states that they are suitable for 3-core polymeric power cable systems and indoor / cabinet mount installations. Power and Cables+23M Multimedia+2

What to Check / Specify

When selecting or working with such a kit, ensure:

Part number / variant matches the cable size (35 sq mm) and insulation outer diameter range.
The kit supports the shield type (tape, wire, UniShield, combination) of your cable.
The voltage class and impulse rating meet or exceed your systems requirements.
The kit is indoor rated (or indoor + cabinet mounting) if installation is inside a switchgear or enclosure.
Kit includes breakout boots (for splitting three cores) and armour continuity parts if needed.
The installation instructions are followed: surface cleaning, proper positioning, removal of the core or support to allow the silicone body to shrink uniformly.
Storage and shelf life limits are respected.
