The Isolator, Solid Link shall be designed and constructed in accordance with 129 and IEC 60694.

The isolating link shall be of the vertical opening, designed for single phasemanual operation. It shall be easily removed and replaced by using a portable operating rod.

The isolating link shall incorporate double porcelain insulators to suit voltagerequirements and mounted on hot dipped galvanised steel under base suitable vertical mounting.

The isolating link shall be arranged so that each unit is mounted independently 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 submitted shall indicate all the applicable mounting positions.

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.

All steel parts shall be hot dip galvanized to BS 729. The minimum coating of galvanizing required is 80 microns.

The solid link shall be removable from the mounting by use of operating rod. All current carrying parts of the isolator shall be made of high conductivity material.

The isolator shall be fitted with clamp connectors for Aluminium (ACSR) conductor of up to 18.2mm diameter.
