SGD LA GRANJA Vidriería, S.L. is the leading industrial concern in the country dedicated to the manufacture of hollow glass and pressed articles. INSULATORS are one of the most technically orientated of these products and enjoy a major international presence. SGD LA GRANJA Vidriería industrial installations have the technological high level. Also it participates in the programs of R+D of SGD, leading to a constant update and renovation of the production facilities and assuring sufficient capacity to attend to market demand and maintain commercial positions. More than 290 years experience in glass manufacturing and the leadership in the sector guarantee our industrial activity To this end, our Group makes, year alter year, important investments to incorporate the latest developments in automation into its production methods and to provide its high tension electrical testing laboratory with de equipment meeting the international requirements of the Electrical Sector. Factory at LA GRANJA (Segovia) where the insulators are produced since 1932 2 AN INTERNATIONAL VOCATION A commercial policy of expansion and coverage of all markets T he activities of SGD LA GRANJA VIDRIERÍA, S.L. are not confined to the local Spanish market but extend throughout the world. A highly specialized human team, commercially very dynamic, offers to the international market products which are highly competitive in price, quality and service. SGD LA GRANJA VIDRIERÍA, S.L has already exceeded the figure of 80 million INSULATORS (210.000 Tons of glass), installed in electrical lines throughout the World, and the increasing volume of its exports in the last few years surpasses the 50% of its turnover. Our glass INSULATORS have won wide international recognition having been specified by many different countries for their transmission lines, thereby contributing to the task of carrying the electrical power wherever it may be necessary for industrial development and social welfare.

Whit the ANNEALING treatment of the glass, internals tensions created during fabrication are eliminated. In this process the temperature is raised sufficiently to relieve tensions but not enough to cause deformation. Then follows a slow cooling process to avoid the appearance of temperature gradients that could create new tensions. This treatment improves the glass properties and above all its mechanical characteristics. The present range RIGID insulators are considered ideal for the use to which they are destined, both for their properties and their dimensions. In 1959 the production of string insulators began. Better known as BALL and SOCKET insulators – also called SUSPENSION insulators – they are made from toughened glass and are a direct result of the research and development on this type of glass, applied to this kind of product. TEMPERING consists in a thermal treatment given to the glass, with a first equilibrium stage to homogenize temperature and a second stage where the outside of the pieces are rapidly cooled in order to create surface compression and internal tension. This provides the glass with many advantages and improved resistance to mechanical and thermal strains. The tempering process gives the glass a great structural resistance, but at the same time demands a very high level of quality, during both fabrication and the inspection stages to prevent defects, in order to ensure that the insulators are reliable for the function they have to perform.. The range of SUSPENSION insulators comply with the main national and international standards: • IEC (International Standards) • ANSI (American Standards) • BS (British Standards) 5 6 THOUHENED GLASS SUSPENSION INSULATORS Characteristics and range of use 8 String Electrical performances 10 Suspension Insulators classification 15 TECHNICAL DATA 16 IEC standards insulators: 16 Standard 16 Anti-pollution 19 Aerodynamic 22 Spherical 24 ANSI standard insulators: 25 Standard 26 Anti-pollution 27 Clevis and tongue coupling insulators 29 BS Standard insulators: Standard 30 30 7 CHARATERISTICS AND RANGE G ENERAL CHARACTERISTICS AND PERFORMANCE. As we have seen, toughened glass insulators have a great resistance due to the thermal treatment they receive. But besides this property there are many other advantages such as their resistance to ageing, even when submitted to great mechanical stress.. On the other hand, their dielectric resistance is very high on account of the glass homogeneity, which makes them practically proof against perforation. Moreover, toughened glass insulators possess another very important advantage consisting in the fact. That a whole glass insulator is always a “healthy” insulator, which facilitates the inspection of the electrical lines. In case of breakage of a glass disc, caused by any incident, the glass shatters into small pieces but the mechanical resistance of the resulting insulator “stump” is practically the same as unbroken insulator. The string of insulators therefore keeps most of its original mechanical properties until such time as the defective insulator can be substituted. S USPENSIONS INSULATOR COMPONENTS Suspensions insulators are componed of the following elements:: • A toughened glass dielectric, with the appropriate characteristics and form for the conditions of the environment in which they have to work. • A malleable cast iron cap, hot dip galvanized. • A forged steel pin, hot dip galvanized. • The cap and pin are joined to the glass disc with a special aluminous cement with the adequate properties to support the termo-mechanical strains during manufacture and use.. • Finally, the capo f the insulator is provided with a locking device (split pin) made from stainless steel or phosphorous bronze ensuring a positive coupling between the string elements.. Also, the pins of tose insulators for use in direct current or high pollution applications can be protected, if required, with a sacrificial zinc sleeve. The cap f insulators with clevis and tongue coupling is provided with a forged steel bolt with a split pin. 8 Exceptional resistance to ageing combined with dielectric and mechanical resistance are the main characteristics of our insulators R ANGE OF USE SGD LA GRANJA range of suspension is in accordance with the principal nacional and international standards: IEC, ANSI,BS, NF, UTE, UNE, DIN, etc. Each standard is subdivided into four insulator groups, classified according to the different forms of the glass disc as required by different environment conditions. These four groups are: • Standard insulators They are most common and used on low pollution lines. • Anti-pollution insulators With two recommended different forms for middle and high pollution zones. Their greater creepage distance allows to reduce the effects of pollution without increasing the length of the string. • Aerodynamics insulators These insulators are highly recomendable in desert applications. Due to their wholly flat dielectric profile, the absence of ribs makes difficult the buildup of deposits on the dielectric due to the clearing action of wind and rain. They may also be used in areas subjected to critical industrial pollution (or combined industrial and desert pollution). • Spherical insulators As with aerodynamic insulators, the lack of ribs on the piece of glass hinders accumulation of residues on the dielectric, facilitating the rain and wind clearing effects. In addition, their spherical configuration makes them also more resistent to vandalism. Finally, within each subdivision, a large range of mechanical resistances exists for each standard and insulator form, going from 40 to 300 kN and fully covering the different requirements and possibilities of electrical lines.,. D IMENSIONAL, ELECTRICAL AND MECHANICAL CHARACTERISTICS Both the guaranteed mechanical and electrical values for each insulator are those recommended by IEC, BS and ANSI standards. Similarly, the dimensional values (such as diameter, spacing, coupling standards, creepage distance, etc.) are in conformity rigorously with the specified standard. 9 STANDARD MODELS FLASHOVER VOLTAGES STRING ELECTRICAL PERFORMANCES ACCORDING TO IEC-383 AND BS-137 PART 1 STANDARDS kV Ø x S: 175 x 100 mm.
