Welcom to QINGDAO MEGATRO HOLDING CO.,LIMITED
The work at the Grant substation seems to be drawing to a close. Looks like they relocated the 'wave trap' up onto the switch tower to free up space at ground level; one CCVT that used to be on the east side of the original 115kV switch has similarly been moved to the north side to mirror the location of the one on the new tower. Also, they finally got rid of the awkward corner into the sub and made the sub a full loop on the 115kV circuit.
Seems they have only a few minor cleanup things to do before they bring the 34.5kV side online. Then we wait and see what happens next.

Oh, and the idle 69kV line to the south is STILL in the same shape it was after the April ice storm!
115KV three dead end steel pole and switch substation framework
This photo refers to our 115KV three dead end steel pole and switch substation framework. These three poles as dead end structure and being single circuit line, beside three poles are switch substation framework, which switch 115KV to 69KV transmission line again.
These 115KV three dead end poles are made of polygonal monopole, and often used in city power transmission grid, with little space, economic and lower cost. Now MEGATRO can produce distribution pole with some type as follow:
(1) Flange connection
(2) Slip joint
(3) Step type
(4) Stagger type
(5) Others
For this 115/69KV substation framework, its features as follow:
This substation structures were made of angle steel, square pipe, channel steel or others, with features as follow:
Custom designed to meet your dimensional requirements
Certified drawings & calculation package provided
Galvanized to ASTM A123
Design codes and specifications:
Industry: NESC, IEEE standard 605, and ASCE Manual 113
Wind: per 2009 IBC & ASCE/SEI7-05
Seismic: per 2006 IBC section 1613, ASCE 7-05 section 15.1.3 &12.8

Since 2004, our MEGATRO begin to produce and design every type of steel pole and substation for our overseas clients. MEGATRO can optimize design, to set a compact, narrow base, the tower design not only advanced but practical, with an emphasis on economic rationality to ensure safe and reliable operation. Today, with over 10 years of experience and our commitment to excellence, MEGATRO remains an industry leader in the manufacture and design of steel tubular & monopole structures for all Highway, Municipal, Custom, telecom, lighting and electric Utility applications. MEGATRO has a complete staff of professional engineering personnel trained in the PLS Pole program and three different manufacturing processes for producing steel towers, poles and other supports. We utilize the latest versions of PLS-CADD, PLS-POLE, TOWER, AutoCAD and other CAD software.
MEGATRO is one of the few manufactures who assemble a face of 115KV three dead end poles. This attention to quality may not be the cheapest process but it does insure every tower meets our high standards of quality. And it helps to reduce on-site construction cost due to mismatched assemblies. MEGATRO 115KV three dead end poles systems can accommodate a variety of cross-arm and other accessories.
After fabrication 115KV three dead end poles and 115/69KV substation frameworks are delivered to the galvanizing facility to be Hot DIP Galvanized. Towers are processed through the facility by Caustic Cleaning, Pickling, and then Fluxing. These strict procedures insure years of maintenance free towers. Even we take secondary finish for client again, which as duplex surface treatment.
