If required.The following documents were referred to during the preparation of this specification. In case of conflict, the provisions of this specification shall take precedence.IEC 129:1975: Alternating Current Disconnectors (Isolators) and Earthing SwitchesIEC 60694:2002: Common Specifications for High Voltage Switchgear and ControlgearBS 729: Hot dip galvanized coating on iron and steel articlesIEC62271-102Isolator (Disconnector) - a mechanical switching device which provides, in the open position, an isolating distance in accordance with Electrical Safety requirements.SERVICE ConDITIONSThe isolator shall be suitable for continuous operation outdoors in tropical areas at altitudes of up to 2200m above sea level, humidities of up to 90%, average ambient temperature of +30ºC with a minimum of -1ºC and a maximum of +40ºC and heavy saline conditions along the coast.4.2. DESIGN AND CONSTRUCTION4.2.1 The Isolator, Solid link shall be designed and constructed in accordance with IEC 129 and IEC 60694.4.2.2 The isolating link shall be of the vertical opening, designed for single phase manual operation. It shall be easily removed and replaced by using a portable operating rod.4.2.3 The isolating link shall incorporate double porcelain insulators to suit voltage requirements and mounted on hot dipped galvanised steel under base suitable for vertical mounting.4.2.4 The isolating link shall be arranged so that each unit is mounted independently on an angle bracket. It shall be supplied complete with the angle bracket and accessories suitable for mounting on 'U' type steel channel. The drawings to be submitted shall indicate all the applicable mounting positions.4.2.5 The isolator shall be designed such that in fully open position, it shall provide adequate electrical isolation between the contacts on each phase. It shall conform to the requirement as single point isolation for safety.4.2.6 All steel parts shall be hot dip galvanized to BS 729. The minimum coating of galvanizing required is 80 microns.4.2.7 The solid link shall be removable from the mounting by use of operating rod.4.2.8 All current carrying parts of the isolator shall be made of high conductivity material.4.2.9 The isolator shall be fitted with clamp connectors for Aluminium (ACSR) conductor ofAluminium (ACSR)conductor of up to 18.2mm diameter.The rating of the complete isolator shall be as follows: -Rated voltage36 kVRated frequency50 HzRated lightning impulse withstand voltage200 kVRated power frequency withstand voltage, dry95 kVRated normal current400 AmpsRated short time withstand current for 3 sec, min.18.0 kAMinimum creepage distance of insulators900 mmSOLID linkS 11KVN/ODETAILDATA1DescriptionSolid link assembly complete with linkrated at 200A and mounting bracket to PIESA 002.
