TECHNICAL SPECIFICATIONS FOR CAPACITOR VACUUM SWITCHES
The new capacitor vacuum switch shall comply with the last revision of, ANSI 37.66 standard for heavy-duty operation in capacitor–switching applications for the hardest climatic conditions
and IEEE 37.66 Class 2 restrike rating. The new overhead pole mounted capacitor vacuum switches shall be suitable for use on DME’s 13.2/7.62kV 4-wire Grounded Wye primary system.
Three vacuum switches will be used to operate three-phase pole mounted, 600 and 1,200kVAR capacitor bank assemblies that utilize 7,960V rated capacitor units.
CONSTRUCTION: Individual Overhead Capacitor Vacuum Switches
The capacitors vacuum switches shall be of the single-phase, solid dielectric, electrically operated type, rated for 7,960 volts designed for use on distribution capacitor installation.
CASING:
The capacitor case material shall be made of advance “hydrophobic cycloalaphatic epoxy’ (HCEP) resin suitable for outdoor service. The switch enclosure roof shall be crowned to prevent
standing moisture.
FINISH:
The capacitor vacuum switch case shall be light gray, Munsell color.
TERMINATION:
The terminal shall be a 200A standard termination located on the top and side of the switch. The terminals shall accommodate AWG No. #8 solid through 2/0 AWG stranded.
OPERATION:
The capacitor vacuum switches shall be capable of electric and mechanical opening operation by hook stick.
CABLE:
The capacitor vacuum switches shall include a weatherproof 5-pin receptacle for control wiring connections to a rack-mounting junction box assembly. The length of the cable shall be
eight feet long. (See attachment below)
VOLTAGE:
The control voltage shall be 120VAC at 60Hz.
RELAY:
A single-pole, double throw relay shall be installed in the actuator to permit opening and closing commands to be transmitted on two wires using a single-pole, single throw switch. An
auxiliary form “C” contact shall be provided on each individual switch to provide “OPEN and “CLOSED” status of the switch main contact.
MOUNTING:
The switch shall have mounting bracket suitable for direct bolting to a metal frame using 5/8” diameter bolts.
ACCEPTABLE MANUFACTURERS
DME will only accept submissions from specific manufacturers listed in the approved manufacturers list below.
ABB
The City has implemented a pre-approval process for substitution commodities and services. The commodity approval form can be obtained via email (laura.hermosillo@cityofdenton.com).
Supporting documentation or samples must be submitted for review by Purchasing, Engineering, field crews, QAG (Quality Assurance Group), and the manager of DME. Testing may be required
and may take substantial time to review. Vendors are encouraged to submit forms and samples for consideration on the next solicitation for similar items.
