3FL silicone long rod insulators –
performance meets durability
Good reasons to use 3FL
Core
The new Siemens silicone long rod in­
sulators (type 3FL) combine the highest
levels of electrical insulation and mechanical tensile strength with a compact, lightweight design. Thanks to their superior design and minimized weight, 3FL long rod
insulators are especially suited for overhead compact-line applications where low
tower design and short line spans are required. They are also more economical to
transport and install.
The core rod is a boron-free, corrosion-resistant ECR2 glass-fiber-reinforced plastic
rod (FRP rod). Due to the extremely high
hydrolysis and acid resistance of the FRP
rod the risk of so-called brittle fracture is
eliminated for 3FL insulators.
Design
The 3FL insulator has a one-piece HTV1
silicone rubber housing made by a highpressure injection molding process. The
HTV silicone is directly molded onto the
core rod by overlapping the triple junction
point and part of the metal end fittings.
The design ensures a total enclosure of the
most sensitive part of a silicone insulator –
the junction zone (metal end fitting/FRP
rod/silicone housing), where the highest
electrical field strength is usually concentrated. This overlapping system eliminates
any possibility of moisture ingress.
2
End fittings
The end fittings, made of hot-dip galvanized forged steel or ductile cast iron, are
directly attached to the FRP core rod by a
circumferential crimping process. Each
crimping process is stringently monitored
with a special control system. A complete
range of end fittings according to the latest IEC and ANSI standards is available with
25, 30, 36 and 50 klbs of SML3. The 3FL is
100% exchangeable and compatible with
existing insulators and line hardware of all
types.
The special design of the end fitting in the
junction minimizes the electrical field
strength and partial discharge inside the
junction zone as well as on the silicone
housing surface, by utilizing an integrated
grading ring. This prevents corrosion of
the insulating material and eliminates the
risk of subsequent failure of the insulator.
3FL – HTV silicone rubber housing
for best pollution performances
The excellent pollution layer characteristics
of the HTV silicone rubber ensure maximum reliability of the 3FL insulator, even
under extreme service conditions. The
high hydrophobicity of silicone rubber prevents the formation of conductive film on
its surface. Even the most severe ambient
conditions, such as salt fog in coastal regions or dust-laden air in industrial areas,
cannot impair the intrinsic hydrophobicity
of the HTV silicone rubber. Surface currents and discharges are ruled out. Neither
water nor dirt on the housing surface can
cause insulator flashovers – a significant
factor for insulator performance.
Siemens quality
According to long-established Siemens tradition and experience in producing highvoltage equipment for more than a century,
each production step for the 3FL – beginning with numerous incoming raw material
inspections, through the assembly of the
individual components, to routine tests of
the finished product – is rigorously monitored and controlled.

Standards and tests
The one-piece housing of the 3FL insulators, i.e. weathersheds and core rod sheath
(coating) is one-piece, and has only one internal interface throughout the whole insulator, namely the boundary interface between the housing and the FRP core rod.
This design eliminates all internal inter­
faces between weathersheds and the core
rod coating. These kinds of longitudinal
interfaces are normally very sensitive to
tangential electrical field stress, which in
worst case scenarios can easily lead to erosion damage of the polymer interfaces. In
particular leading to erosion of the bonding between sheds and rod sheath, and
thus damage to the insulator housing.
After numerous electrical calculations regarding E-field distribution along the insulator, and the connection zone on the
high-voltage side in particular, the design
of the 3FL insulator was optimized for
maximum reduction of electrical field
stress, reduced corona effect, and minimized RIV4 value. Two design keys ensure
improved life expectancy by reducing electrical field stress in the triple point and on
the silicone surface:
All 3FL long rod insulators are designed
and completely tested in compliance with
the latest ANSI C29.11 and ANSI C29.12
standards for composite suspension
insulators.
Furthermore, the junction point in the connection zone, where all three elements
(FRP rod, metal end fitting, and silicone
housing) meet each other, is absolutely
water- and air-tight sealed during manufacturing by using an overmolding housing system. It totally encloses this junction
point with the HTV silicone rubber of
the housing itself. The highest bonding
strength of the one-piece HTV silicone
housing to the FRP core rod combined with
the overmolding design system prevent
moisture ingress at the connection zone
of the insulator.
The spherical-shaped rim of the end fitting inside the housing homogenizes
the E-field distribution on the high-voltage side of the 3FL insulator with an integrated grading ring up to 170 kV.
The overmolded design system and the
silicone housing shape at the connection zone reduce the electrical field
strength inside the housing, at the inner
triple point in particular, as well as on
the silicone surface directly. This by
displacing the higher electrical field
strength outside the housing (i.e. to the
surrounding air area), and by taking advantage of the higher silicone relative
permittivity.
In this way, 3FL insulators can be applied
on 170 kV systems without the need for
additional grading/corona rings.
Each Siemens 3FL insulator that leaves
the factory is routinely tested with a corresponding mechanical tensile test load of at
least 50 percent of the defined SML load
for at least ten seconds.

Marking and nameplate of 3FL insulators
A nameplate is installed on each 3FL insulator when it successfully
passes the mechanical routine test. It is a weather- and UV-proof
stainless steel band with locking system, placed on the ground
end fitting of the insulator. The etched marking includes: catalog
number, SML, RTL, CIF, creepage distance, end fittings designation, and production date code.
Packaging
3FL insulators are packaged in wooden crates with the following
dimensions: width is 44 inches (1,120 mm), height is equal to
or lower than 37.16 inches (944 mm), the length is determined
by the insulator length. The maximum weight of one crate is
2,000 pounds (900 kg).
