3FL long rod insulators can be used either as suspension or tension insulators 3FL a superior design to meet the highest requirements HTV silicone rubber for best pollution performances Brittle-fracture-resistant ECR-glass FRP rod One-piece HTV silicone rubber housing Junction zone Junction point: FRP rod/metal fitting/silicone (triple point) completely embedded in the silicone housing Integrated grading ring reduces the electric field inside and outside the junction zone 3FL silicone long rod insulators performance meets durability Good reasons to use 3FL The new Siemens silicone long rod insulators (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. Design The 3FL insulator has a one-piece HTV 1 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. Core The core rod is a boron-free, corrosion-resistant ECR 2 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 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 SML 3. 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 s 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. 2
E-field distribution (%/mm) in silicone housing and in FRP core rod at 3FL insulator high-voltage end E-field distribution (%/mm) at 3FL insulator high-voltage end 3FL Housing (HTV SiR) FRP rod Silicone surface Sphericalshaped rim Connection zone End fitting Inner triple point Maximized service life No moisture ingress 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 interfaces 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. 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. Minimized electrical field strength 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 RIV 4 value. Two design keys ensure improved life expectancy by reducing electrical field stress in the triple point and on the silicone surface: 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. 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 corresponding mechanical tensile test load of at least 50 percent of the defined SML load for at least ten seconds. 1 HTV: High-temperature vulcanizing 2 ECR glass: Electrical- and corrosion-resistant glass 3 SML: Specified mechanical load 4 RIV: Radio interference voltage Product standards ANSI C29.11 Tests for Composite Suspension Insulation for Overhead Transmission Lines ANSI C29.12 Insulators Composites Suspension Type ANSI C29.1 ANSI C29.2 Test Methods for Electrical Power Insulators Insulators Wet-process Porcelain and Toughened Glass Suspension Type 3

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, 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). 11
