SUBSTATIONS. Based on the number of high voltage substations weighted for Voltage (Voltage < 500kv = 1; Voltage >= 500kv = 2). Used primarily for the allocation of related engineering and technical support for transmission and distribution substation operations and maintenance as well as for engineering and project management associated with substation construction. Based on two components: Transmission Line Miles (30% weighting) and the Number of High Voltage Substations (70% weighting). Used primarily for the allocation of the costs associated with the support of the transmission and distribution function that has both a transmission line component as well as a substation or load component.
SUBSTATIONS. In the event that the Employer should establish substations which require xxxxxxx, the personnel shall be solicited from volunteers first. In the event that voluntary personnel with the required training and experience are insufficient, assignment of qualified personnel shall be made by the Sheriff after giving consideration to the needs of the Department and the personal circumstances of the officers involved.
SUBSTATIONS. (1)(i) Plans and speci- fications for all new substations must receive RUS approval prior to request- ing bids on contracts or commence- ment of force account construction, unless:
(A) The substation design has been previously approved by RUS; and

Specifications and drawings, including a one-line diagram, plot and foundation plan, grounding plan, and plans and elevations of struc- ture and equipment, as well as all other necessary construction drawings, in sufficient detail to show phase spac- ing and ground clearances of live parts;
SUBSTATIONS. Generally, specifications of equipment in this subsection must be respected, and any modification or change to them proposed by the Concessionaire must be previously reviewed and approved by the Grantor. Yard equipment specifications shall comply with voltage and current levels indicated in paragraph c) Voltage and Insulation Levels and d) Current levels of section 2.3.4.
a) They must comply with the minimum design criteria established in Xxxxxxx 0, Xxxxx 0 xx XX- 00.
b) The corresponding IEC standards will be applied for each equipment and / or those that comply with them.
c) Cabinets and control boxes shall have an IP-54 degree of protection.
d) All metal parts shall be hot galvanized according to ASTM or VDE Standards, and windings shall be of insulated copper.
e) Circuit breakers
SUBSTATIONS. Substations will be designed and projected using the switch and one half connection layout for 500 kV, and the double bar layout with transfer switch for 220 kV. Thus, the Concessionaire will provide any necessary spaces and areas for these types of layouts. Generally, the areas planned for future expansions should be adequately explained and leveled.
2.3.1 Expansion of the de Colcabamba 500 kV / 220 kV substation
2.3.1.1 Facilities under construction
a) Two (02) cells for connecting the line to the Poroma S.S., which is equivalent to 2/3 of the switch and one half layout diameter.
b) Two (02) cells for connecting the 500/220/33 kV autotransformer bank of, equivalent to 2/3 of the switch and half layout diameter. Conventional equipment with external insulation will be installed:
c) One (01) cell for the connection of a line reactor, at the output in 500 kV to the Poroma S.S.
d) One (01) 500 kV line reactor of 171 MVAr, consisting of 3 single-phase units of 57 MVAr each, plus one reserve unit and one neutral reactor. e) One (01) 500/220 / - kV and 750/750 / - MVA (ONAF) autotransformer bank, consisting of 3 single-phase units of 250 MVA each, with star/star/delta connection group (Y / and / d), plus a reserve unit. The 220 kV bar system and yard equipment will have a double bar connection layout with transfer switch, comprising the following facilities: • One (01) cell for connecting the link to the Xxxxx Xxxxxx 220 kV. S.S. • One (01) cell for the 220 kV side connection of the 500/220 kV autotransformer bank. • One (01) cell for the 220 kV bar coupling. • One (01) single-phase 15 Ohm series reactors bank, of the air core type, to be installed in the link cell to the Xxxxx Xxxxxx 220 kV. S.S. Likewise, reserve spaces are planned for future 220 kV and 500 kV facilities. The 500 kV and 220 kV described equipment of these facilities under construction is informative. Before carrying out the expansion, the Concessionaire shall verify the definitive characteristics of this substation in coordination with CTM.
2.3.1.2 Facilities included in the expansion
a) Expansion of the bar system in double bar layout with switch and one half.
b) Two (02) cells for connecting the line to the Nueva Yanango S.S., which equals 2/3 of the diameter of the switch and one half layout. These cells must be compatible with the GIS cells provided in the original Colcabamba substation design. The following conventional equipment with external insulation will be installed:
c) One (01) cel...
SUBSTATIONS. The yard equipment specifications shall meet the voltage and current levels set out in Item c) Voltage and Insulation Levels and d) Current Levels of Point 2.3.
a) They shall meet the minimum design criteria set out in Chapter 1, Annex 1 of PR-20.
b) The IEC standards applicable to each equipment and/or that comply with them shall be applied.
c) The shelves and control boxes shall have an IP-54 protection degree.
d) All metal parts shall be hot-dip galvanized according to the ASTM or VDE standards, and the windings shall be made of insulated copper.
SUBSTATIONS. Two new and one existing substations are involved. Each new substation uses 225 MVA 230-kV/92-kV transformer banks with 230-kV and 92-kV switchyards. Each switchrack includes wide flange steel structures for line, bus and transformer dead-ends, a suspension bus system with mid-span taps for line and transformer connections, circuit breakers and air disconnets for line and equipment switching, fault protection and isolation during maintenance and necessary coupling capacitors, wave traps and potential devices for metering and control. Each substation will have a relay/control house equippedd for remote operation. EXHIBIT 4
