61 -- PHASE-TO-GROUND LINE TUNER Sol SB-95-0062 due 091595. Contact Etta Mae Track/Contract Specialist, Eddie Quotskuyva/Contracting Officer/(602) 379-6760. The Bureau of Indian Affairs is resoliciting to procure phase-to-ground line tuner for San Carlos Irrigation Project (SCIP) at Coolidge (Pinal County), Arizona. The procurement consists of 35 each line tuners for use on the 69kV transmission system. The line tuners shall meet all applicable IEEE and ANSI standards. The frequency range shall be 30 kHz to 535 kHz, use with coupling capacitor of 1000 pF to 20,000 pF, and must not pass any frequencies below the field adjustable cutoff frequency. The turner coil shall wound inductance to be on a phenolic form, winding taps to be available for coarse tuning, and adjustable ferrite core to be available for fine tuning. The power rating must allow continuous power of up to 50 watts R.M.S., and P.E.P. of up to 100 watts. The transformer must have magnetic core with two windings, taps to allow matching a 50 ohm coaxial cable to an HV line characteristic impedance of 50 to 2000 ohms. The ambient temperature range shall range of -20 degrees C to +60 degrees C (-4 degrees F to +140 degrees F), and humidity up to 95% at +40 degrees C (104 degrees F). The capacitors must be high grade mica insulated phenolic molded capacitors, connection straps to allow series-parallel connection, and internally mounted knife blade switch. The lightning protection shall be equipped with an MOV type of lightning arrester and arrester shall meet all applicable IEEE and ANSI standards. The line tuners shall have 4 modules mounted on a steel or aluminum plate, have flexibility for future use by allowing up to 8 modules, and be suitable for surface mounting, particularly on the exterior of the base box of the capacitor voltage transformer. The product shall be delivered within 120 calendar days after award of contract. The solicitation will be available by 18 Aug 95. No telephone requests. Only written or faxed requests received directly from the requestor are acceptable. Fax number is 602/379-6763.
