Cold Shrink Silicone Rubber 8560
Series 3/C Cable Breakout Boots
3M 8561 through 8565 Silicone Cold Shrink Cable
Breakout Boots are a series of open-ended molded rubber
sealing assemblies that are factory expanded and mounted
on removable inner-supporting plastic cores. They are
supplied for field installation in a pre-stretched condition.
The supporting cores are removed after the seal has been
positioned for installation around the breakout area of a
three conductor cable. Core removal allows the silicone
rubber boot to shrink down to a predetermined diameter;
creating an environmental enclosure for individual cable
phase legs and the overall cable jacket.
8560 Series Breakout Boots are designed to protect the
phase leg breakout of 3/C medium voltage power cable
from exposure to moisture, contamination, corrosion,
ozone, ultra-violet radiation, physical contact and other
hazards associated with 3/C termination operating
environments. 8560 Series Breakout Boots can be used in
conjunction with 3M Silicone Rubber Cold Shrink
Rejacketing Sleeves for 3/C shielded power cable
terminating applications.
Features and Benefits:
• Versatile; installs quickly and accommodates a wide
range of cable sizes.
• Simple hand application; no need for special installation
tools.
• No torches or heat required.
• No specific user skills or craftsmanship required.
• Excellent resistance to ozone and ultra-violet radiation
• Good solvent resistance; compatible with industry –
approved cable cleaners.
• Excellent thermal stability.
• High dry and wet insulation resistance.
• Highly flexible; accommodates all power cable supplier
bend radius recommendations.

3/C Phase Rejacketing System
3M RJS Series Rejacketing Sleeves are designed so that 3M
Cold Shrink QTII & QTIII Silicone Rubber Terminations
can be used on 3/C (three conductor) medium voltage
shielded power cables of tape shield, wire shield, armored
and non-armored configurations. RJS Rejacketing
Assemblies are a series of silicone rubber insulators
incorporating an inner-expandable polyester braid designed
to reduce sliding friction and deliver the insulator onto the
cable. Rejacketing sleeves are designed to protect the phase
legs (core) of 3/C shielded power cable from exposure to
moisture, corrosion, ozone, ultra-violet radiation, physical
contact and other hazards that are associated with
termination operating environments. Rejacketing sleeves are
designed to be used in conjunction with 3M Cold Shrink
Breakout Boots and Silicone Rubber Terminations.
