Preliminary Single Line Design

Preliminary Single Line Design

Hello Everyone,

I am looking to develop a single line showing the installation of a new 66kv sub and a ten mile long cable to a platform. Cable will terminate in a new power distribution center. Incoming line from SCE is at 66KV

Here is some thought I have:

1)New substation at 66KV to a fused interrupter switch and then 69KV cable to the platform
2)New Sub to XFMR: 66KV to 35KV and use a 35 KV cable to the platform.

What thoughts do you guys have?

Also, design wise and cost wise, what would be the best way of going about this.

Appreciate the help
