CONSTRUCTION

GTDSOFI 30 size 41

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.
