Project Overview • Customer: Perm Energo

• Project: Perm - Tets-6

• Location: Perm, Ural region, Russia




• Voltage: 110 kV

Solution: 3M ACCR 300-T16 - Ostrich

Results: • Increased ampacity from 450 A to 700 A to

serve an expanded combined cycle power plant

• Used exiting rights of way to avoid logistical and permission issues in a crowded urban area

“In cooperation with IDGC of the Ural, we have found the best power output option, which is cheaper and more effective by its implementation at the same time. It was very vital for us to timely receive lines with enhanced capacity, so network companies successfully managed this challenge and performed their obligations at a high-quality level and right on time”,

Andrey Vagner, First Deputy General Director of IES

Project Profile: New Construction in an Environmentally Sensitive

Area and River Crossing

Project Overview:

• Customer: CTT (Cross Texas Transmission)

• Project: Red River Crossing

• Location: Texas



• Line length: .74 miles (1.19 km)

• Voltage: 345 kV

Solution: 3M ACCR 1622-T13 TW (823 mm2)

Results: • Kept tower height low enough to avoid FAA compliance

issues

• Avoided new towers and larger foundations in the floodplain, because longer spans could be used

• Avoided permitting issues

• Part of CREZ (Competitive Renewable Energy Zone) projects to enable renewable energy development in Texas

Project Overview:

• Customer: Yinchuan Power Utility

• Project: Yinchuan Substation Part 1 & 2

• Location: Yinchuan, Ningxia Province, China


• Length: • Conductor length: .81 miles (.1.3 km)

• Line length: .27 circuit miles (.43km)

• Voltage: 220 kV

Solution: 3M ACCR 795-T13 and 591-T13

Results: • Doubled capacity within existing substation frame

• Installed in 9 days

3M™ ACCR

54

Project Profile: Large Ampacity Increase

Project Overview:

• Customer: City of Palo Alto

• Project: Park Blvd. – Encina

• Location: Palo Alto, CA




• Voltage: 60 kV


Results: • Increased ampacity by 80% on line in a highly

developed urban area

• Matched the existing sags and tensions

• Maintained clearance from underbuilt line

• Enabled the use of existing towers along narrow right of ways and city streets

“With 3M ACCR we were able to avoid replacing all of the

structures along the route of our sub-transmission reconductoring

project. 3M’s technical staff made the procurement easy and

error free,” Jim Bujtor, Sr. Electric Engineer, CPAU.
