The inner diameter shall be sealed off at 10 5/8” The bolt center diameter of the outermost flange shall be 23 3/8” There will only be 6 bolt holes on the outermost flange, separated by 60 degrees The outer diameter of the bushing shall be a 19”

The bushing shall meet the following minimum salient characteristics:

Rated for use on 10.5 inch round aluminum, 13.8KV, 7000 Amp rated bus

110KV BIL

Able to withstand a 1 minute 50KV AC dry over-potential test Rate for a 65 degrees Celsius rise over ambient temperature Rated for ambient temperatures ranging from -30 to 40 degrees Celsius Polymer, porcelain or government approved alternative material

The assembly shall include the insulator and all auxiliary equipment needed to install. This shall include gaskets, washers, bolts, and all other items.

3.2 T1 Standoff Bushing Assembly (GE T1)

Provide a quantity of nine direct replacement bus support insulator assemblies for the one shown in section J-J of drawing 0544DO815. Drawing L-82390 will be used for reference for the standoff insulator with the following modifications:

The outer diameter will be 8” max The insulator shall be 6” tall The top of the insulator shall have a centered 3/4"-10 bolt hole that goes 3” into the insulator

In addition to the above requirements the standoff bushing assembly shall meet the following minimum salient characteristics:

Rated for use on 10.5 inch round aluminum, 13.8KV, 7000 Amp rated bus

110KV BIL

Leakage Distance 19.5 inches Rated for 4000 lb cantilever strength at 2 1/2" above insert Able to withstand a 1 minute 60KV AC dry and dew over-potential test Rate for a 65 degrees Celsius rise over ambient temperature

Polymer based bushing or government approved alternative material

The replacement insulators shall meet or exceed the mechanical strength requirements stated on the attached drawing, file no. L-82390. The replacement insulators shall not create a larger gravitational weight than the existing insulators. The replacement insulators shall not create larger dynamic loads than the existing insulators. The dynamic loads include but are not limited to short circuit forces (if applicable).

Finally, the replacement insulators will not alter the support conditions. Thermal expansion loads, if applicable shall also be taken into account.

The assembly shall include the insulator and all auxiliary equipment needed to install the assembly as shown on the drawing. This shall include gaskets, washers, bolts, and all other items.

3.3 T2 Through/Seal Off Bushing Assembly (HK Porter T2)

Provide a quantity of nine direct replacement seal-off bushing assemblies with the characteristics shown in drawing T-157059. In addition, the bushing assembly shall meet the minimum salient characteristics:

Rated for use on 6 inch square aluminum, 13.8KV, 7000 Amp rated bus

110KV BIL

Able to withstand a 1 minute 50KV AC dry over-potential test Rate for a 65 degrees Celsius rise over ambient temperature

Polymer based bushing or government approved alternative material

The assembly shall include the insulator and all auxiliary equipment needed to install the assembly as shown on the drawing. This shall include gaskets, washers, bolts, and all other items.

3.4 Isophase Bus End Bell Gaskets

Provide a quantity of fifty end bell gaskets with a splice kit and fifty split cover gaskets as shown in section “x-x” of drawing 0544D0815.

The material for the new gaskets shall be of the type used for gasketing applications. The material shall be resistant to temperatures between -103 to 450 degrees F and shall be UV/Ozone resistant. New gaskets' material shall be closed cell silicone sponge medium density or approved equal.
