3FL Silicone Long Rod Insulators for Transmission Lines 69–500 kVStrong performance – reliable service

3FL silicone long rod insulators – performance meets durability

Core

The core rod is a boron-free, corrosion-re-sistant 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.

End fittings

The end fittings, made of hot-dip galva-nized 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 lat-est 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 maxi-mum reliability of the 3FL insulator, even under extreme service conditions. The high hydrophobicity of silicone rubber pre-vents the formation of conductive film on its surface. Even the most severe ambient conditions, such as salt fog in coastal re-gions or dust-laden air in industrial areas, cannot impair the intrinsic hydrophobicity of the HTV silicone rubber. Surface cur-rents 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 tra-dition and experience in producing high-voltage equipment for more than a century, each production step for the 3FL – begin-ning with numerous incoming raw material inspections, through the assembly of the individual components, to routine tests of the finished product – is rigorously moni-tored and controlled.

Good reasons to use 3FL

The new Siemens silicone long rod in-sulators (type 3FL) combine the highest levels of electrical insulation and mechani-cal tensile strength with a compact, light-weight design. Thanks to their superior de-sign and minimized weight, 3FL long rod insulators are especially suited for over-head compact-line applications where low tower design and short line spans are re-quired. They are also more economical to transport and install.

Design

The 3FL insulator has a one-piece HTV1 silicone rubber housing made by a high-pressure 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 concen-trated. This overlapping system eliminates any possibility of moisture ingress.

3FL long rod insulators can be used either as suspension or tension insulators 3FL – a superior design to meet the highest requirements

Standards and tests

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.

Each Siemens 3FL insulator that leaves the factory is routinely tested with a corre-sponding mechanical tensile test load of at least 50 percent of the defined SML load for at least ten seconds.

Maximized service life

Minimized electrical field strength

After numerous electrical calculations re-garding E-field distribution along the insu-lator, 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 mini-mized RIV4 value. Two design keys ensure improved life expectancy by reducing elec-trical field stress in the triple point and on the silicone surface:

The spherical-shaped rim of the end fit-ting inside the housing homogenizes the E-field distribution on the high-volt-age side of the 3FL insulator with an in-tegrated grading ring up to 170 kV.

The overmolded design system and the silicone housing shape at the connec-tion 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 ad-vantage 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.

No moisture ingress

The one-piece housing of the 3FL insula-tors, i.e. weathersheds and core rod sheath (coating) is one-piece, and has only one in-ternal interface throughout the whole in-sulator, namely the boundary interface be-tween 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 ero-sion damage of the polymer interfaces. In particular leading to erosion of the bond-ing between sheds and rod sheath, and thus damage to the insulator housing.

Furthermore, the junction point in the con-nection zone, where all three elements (FRP rod, metal end fitting, and silicone housing) meet each other, is absolutely water- and air-tight sealed during manu-facturing by using an overmolding hous-ing 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.

* Reference section length for insulator configuration with Y-clevis (Y) and Ball (A) end fittings. To obtain the section length of other end fitting configurations please use the section length adjustment table. X1: Upper end fitting (earth side) X2: Bottom end fitting (high-voltage side) X3: Upper corona ring (earth side) X4: Bottom corona ring (high-voltage side)

** To determine the section length for an insulator with a different end fitting combination, please add or subtract the displayed length change in the table above. For configurations not shown, use the catalog number key or contact your Siemens representative.

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 designa-tion, 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).
