GENERAL:     Post type, insulated by brown epoxy resin. (Grey resin on request).
    Types GSS 10, sizes 1 and 2 as well as type GSS 20 size 1 have busbars of nickel plated copper. For dimensions please see
                     overleaf. These bars are guided by caps with appropriate orifices. Caps are of aluminium alloy.
    Types GSSO.. have no busbars. Guiding caps for busbars can be provided on GSSO 10, sizes 1 and 2 as well as on
                     GSSO 20, size 1. Dimensions of available caps are shown overleaf.
    The guiding caps can be shifted to put the busbars either in horizontal or in vertical position. This applies to GSSO.. as
    well as to GSS..

APERTURES:     For available dimensions please see overleaf.
    The inner surface of both the GSSO.. and the GSS.. consists of a brass tube which is fitted with a flexible terminal to be
    connected to the primary conductor to keep the CT on the same potential level. (GSS.. are supplied with that terminal
    already connected to one of the busbars).

SECONDARY         TERMINAL     BOX: Of aluminium alloy, with transparent and sealable cover. Grade of protection: IP52 in
    compliance     with DIN 40050 and IEC 529. Terminals are of nickel plated brass of size M6. Each terminal can be earthed
    by means of a “screw-through-connection”     inside the box. Three cable glands Pg16 for cables up to 16mm diameter
    are provided.

BASE:   Of aluminium    alloy.                                                                               MOUNTING:          In vertical position.

CONSTRUCTION

GENERAL:       Bushing type (through-the-wall   type), insulated by weather-proof    cycloaliphatic epoxy resin. Colour of resin: brown.
   (Grey resin on request). Special features: Good ability to withstand ultra-violet rays. Practically non-inflammable.     Cycloaliphatic
   resin does not split off carbon under the influence of surface ionisation.
   Generally without busbars. Caps with orifices to guide the primary conductor can be provided for outdoor units. Outdoor-
   indoor units have such guiding caps as a regular equipment. The caps, of aluminium or resin, prevent ingress of water to
   the building. Dimensions of required orifices to be advised when inquiring. - Nickel plated copper bars or any other conductors
   can be provided to customer’s specification.       - For airtight installation we can modify the outdoor-indoor    units appropriately.

APERTURES:     Type GTDSOF 1 O/O: 134mm diameter. Other types: 205 or 297mm diameter.
   The inner surface consists of an aluminium tube which is fitted with a flexible terminal for connection         to the primary conductor
   to keep the CT on the same potential level.

SECONDARY       TERMINAL     BOX: GTDSOF 1 O/O: The terminal box is part of the resin body (homogeneous           casting). The other
   designs have a terminal box of aluminium alloy. All boxes have a sealable cover. Terminals are of nickel plated brass of size M6.
   All terminal boxes are provided with cable glands of size Pg16. Location of glands is shown overleaf. Pg16 is suitable for
   cables up to 16mm diameter (outdoor-indoor       units) and for cables of 10 to 14mm (outdoor units). Optional for outdoor units:
   Pg21 for cables of 14 to 18mm diameter. On request: X-inch-conduit        hubs.
   All the CT’s have secondary terminals which can be earthed inside the terminal box, either by means of a “screw-through-
   connection” or by a link.

MOUNTING:     The resin flange of the outdoor CT’s is equipped with four corner pieces of aluminium alloy. Outdoor-indoor  units
   have a projecting flange of aluminium alloy. This flange prevents ingress of water to the building. Mounting in any position.
  (When outdoor units are horizontally mounted: terminal box downwards).

EARTHING: Type GTDSOF IO/O can be earthed at one of the corner pieces. The other types have one earthing bolt of metric size
   M8 at the terminal box.

MECHANICAL    STRENGTH: When installing our regular equipment, any mechanical forces are to be absorbed by post insulators
   supporting the primary conductor. As a non-standard    option, the CT’s can be equipped with special guiding caps and extra
   strong mounting flanges suitable to withstand mechanical forces up to 6000N.

TROPICALIZED       DESIGN:    On outdoor    units free of charge. On outdoor-indoor      units at a small surcharge.

ADDITIONAL      APPLICATION:     For use as discharge reactors on capacitor banks. When inquiring                     please advise the bank’s Mvar
      rating to be discharged as well as the intended number and time intervals of discharges.

TESTS:    Routine tests to applicable      standard.     Measurement      of internal partial discharges    is performed   as a routine test.

CONSTRUCTION
GENERAL:      Core and windings are completely enclosed in weather-proof       cycloaliphatic epoxy resin. Colour of resin: brown RAL
   8017. (Grey resin on request). Special features: Extremely long creepage distance. Good ability to withstand ultra-violet rays.
   Practically non-inflammable. Cycloaliphatic resin does not split off carbon under influence of surface ionisation. Units are suitable
   use in heavily polluted and coastal areas.

PRIMARY TERMINAL(S):         Stem(s) of 20mm diameter, 55mm long, of nickel plated and tinned brass. Clamp type connectors on
     request. Type GSZF has two fully insulated primary terminals. Type GSEF has one. The other end of the primary winding is
    insulated to withstand a power-frequency   test voltage of 3kV. This grounded end is located inside the secondary terminal box.
    On request: GSEF with insulated neutral terminal in compliance with IEEE (ANSI) and CSA, i.e. the primary winding withstands
    an applied test voltage of 19kV - the neutral end is routed to a separate terminal on the opposite side to the terminal box.

SECONDARY        TERMINAL       BOX: The terminal box is part of the resin body (homogeneous    casting).               The cover is sealable. Grade
   of protection: IP 54 to      DIN 40050 and IEC 529. Terminals are of nickel plated brass of size                    M6. They can be earthed by
   a link inside the terminal   box. One cable gland (for cables of IO to 14mm diameter) and one blind                  plug both sized Pg16 belong
   to the regular equipment.     Optional: plug size Pg21 for cables of 14 to 18mm diameter. On request:                conduit hubs up to one inch.

BASE: Two strong mounting brackets of hot-dip galvanized steel.                           EARTHING:   One bolt M12, opposite to the terminal box.

MOUNTING:      Vertical erect or (terminal box downwards)           in horizontal     position.

COMMISSIONING:         Units are supplied     ready for service. Just connect to system. Special tools are not necessary.
