Product Introduction
OCS is the core power supply equipment in power supply system of electrical railway traction. Its function is to supply power to the running electric locomotive incessantly. Different from the ordinary power transmission line, it must be fixed on the right top of the rail, and then locomotive can get power incessantly through the slip friction between top pantograph and contact wire. So everywhere that electric locomotive running through should span catenary. All catenary installation is hypaethral and it is always affected by kinds of bad weather, as well as its working state is changed with the running of electrical locomotive and has no standby, so working environment for catenary is complex and the request for it is higher. OCS components manufactured by SAITONG introduces and adopts international advanced technology, and optimize the design of key components products according to the technology feature of domestic rail transportation and feature of parallel products. The whole series of products have been homebred, and this caters to the construction and operation of Chinese rail transportation better. Aluminum alloy and copper alloy are adopted much in our product forging, now we have two forging line, and the manufacturing capability hits 2000kms/year. SAITONG is making the core components of Siemens Re250km/h and Re350km/h in China and can produce all catenary components refer to Chinese railway standard; we have passed the test of P.R.C catenary components inspection station. we have the sales ability.

Cantilever support can be made of carbon steel and aluminum alloy. When the cantilever support is made of carbon steel, seamless steel pipes GB/T8162 can be used, but when the cantilever support is made of aluminum alloy, alma Ilium pipes AlMgSilF31 that refer to the standard of DIN 9107 can be used. Its working load is not less than 9.4 kN; the min. breaking load is not less than28 kN.
5. Steady ring
Steady ring is fixed on the cantilever, it provide installation support to binaural sleeve components, such as cantilever support binaural sleeve and inclined cantilever. Steady ring is made of the material of cast aluminum alloy EN AC-AlSi7Mg0.6 that refers to the standard of DIN EN 1706, and is made by metal mould forging technology. The working load is 5.0 kN; the min. breaking load is not less than15 kN; Tightening torques: 70Nm for bolt M16U.
6. Steady Tube, Hook end fitting
Registration arm provides location support to positioner; one end is joint with registration arm while on the other end pipe cap is installed.
Hook end fitting is fixed in the bottom of registration arm to make it join with inclined cantilever.
Registration arm can be made of carbon steel and aluminum alloy. When the Registration arm is made of carbon steel, seamless steel pipes that refer to the standard of GB/T8162 can be used, but when the Registration arm is made of aluminum alloy, alma Ilium pipes AlMgSilF31 that refers to the standard of DIN 9107 can be used.
Hook end fitting is made of the material of cast aluminum alloy EN AC-AlSi7Mg0.6 that refers to the standard of DIN EN 1706, and is made by metal mould forging technology.
The working load is 2.5kN; the min. breaking load is not less than 7.5kN; Tightening torques: 70Nm for bolt M16U.
7. Steady Arm
Steady Arm has below three kinds, straight, angle and curved steady arm. It is used for clamping the contact wire and ensuring the wire is fixed towards the direction of the line under the request of design. In overlap and curve section of the line, angle and curved steady arm and corresponding bracket will be used.
Steady ear, hook end fitting, grooved stud and rectangular pipe are main components of Steady Arm.
Positioner uses CuNi2Si material that refers to the standard of EN 12165.
Hook end fitting uses EN AW-6082 material that refers to the standard of EN 755-2.
Rectangular pipe uses EN AW-6082 material that refers to the standard of EN 755-2.
Hook end fitting, grooved stud cover and Steady ear are produced with precision casting process for metal mold.
Its working load is 3.5kN and the minimum anti-destroy load is not less than 10.5 kN.
8. Drop bracket
Drop bracket is installed on the registration arm with U style bolt, and the hook at the bottom of it is used for the link of hook end fitting. The position of the steady arm can be adjusted by changing the location of U style bolt on registration arm.
Positioner bracket uses EN AW-6082 materials that refer to the standard of EN 755-2 and are made by metal mould forging technology.
Its working load is 3.5kN and the minimum anti-destroy load is not less than 10.5 kN.

Specification and Allocation
Section insulator is composed with insulator body and iron components, includes messenger wire, termination fitting for catenary, catenary insulator, junction components and section insulator suspension equipments. Section insulator is made of copper, stainless steel, copper nickel, and silicon alloy, Insulator on catenary is made of GFRP, conical termination fitting is made of albronze.
Performance
The contact between insulating body of section insulator and pantograph is directly sliding. The insulating body has sufficient ability for anti-arcing and self-cleaning, and has the function to guide the arcing. During the sliding passage of pantograph, no electric breaks appear. The material of section insulator has higher ability of anti-arcing in order to avoid any damage due to burning of all the parts of section insulators. The body of section insulator is made of light alloy material with high mechanical performance and polymerized material with high strength and anti-corrosion material. The assembly is light in weight. The metal connection parts and all the accessories, fastening pieces are made of anti-corrosion material. They can bear the working load reliably with efficient safety factor. The insulating parts of section insulator and MW (including insulating slider) are self-cleaning and water repelling. Service life of the whole set of the section insulator is not less than 15 years.

Technical Parameter
Power frequency dry withstand voltage is 163kV.
Power frequency wet withstand voltage is 132kV.
Full wave impulse withstand voltage is 40 kV. (Standard lightning impulse withstand voltage)
Power frequency pollution withstand voltage is 40kV. (Surface density of salt covering is 0.35mg/ cm2)
Creepage distance is ?1200mm.
Min. failing load is ? 90Kn.
the working load is ? 30Kn.
Performance of anti-vibration ? 2*106 times.
Performance of anti-wear (times of pantograph) is ? 5*105 times.
Minimum of air distance is ? 220 times.
Unit weight is 15.5kg.

Evaluation Methodology Basics: The Nuts and Bolts of Sound Evaluation provides a step-by-step guide for doing a real evaluation. It focuses on the main kinds of "big picture" questions that evaluators usually need to answer, and how the nature of such questions is linked to evaluation methodology choices. Jane Davidson explains how to combine a mix of qualitative and quantitative data with "relevant values" (such as needs) to draw explicitly evaluative conclusions. The book presents readers with useful rubrics and flowcharts that may be used during each stage of the evaluation. Many of the concepts presented in the chapters are illustrated with specific examples from a range of disciplines.

Alpha Lipoic CapsAlpha-Lipoic Acid is a powerful antioxidant that is soluble in both fat and water. It directly recycles vitamin C and indirectly recycles vitamin E, providing additional antioxidant protection. It is also an important component in the energy production process in the cells. Alpha-lipoic acid is a coenzyme that assists in the conversion of pyruvate to acetyl-coA. Acetyl-coA is the beginning point for the Krebs cycle, one of the body's main energy production cycles, which produces the high-energy molecule ATP. Alpha-lipoic acid supports the immune system and also supports healthy liver function.
