| 1. | Please define the statement “IAW Attached PWS”. Is there another document not attached to the positing? |
| * The PWS document is now attached to the solicitation. |
2. CLIN 0002 - It appears this 90-kVA converters is meant to be mobile with caster call outs (Item 16). Can that be confirmed?
| * Negative. 90KVA converters require an 18" riser that bolts down |
| into the cement/ground for sturdiness as the 45KVA units do. |
3. CLIN 0002 - Can you confirmed the input voltage for the 90-kVA converter is 480 VAC, 60 HZ, 3-phase?
| *Correct, same as the 45KVA Converters, input voltage is 480 VAC |
| +/- 10%; 3-phase @ 60 Hz. |
| *If providing a 90KVA unit, it is only for the explosion |
| Proof hangarette that is wired differently than the others. Utilization |
| Of the 90KVA units would power all 4 hangarettes; opposed to having |
| 4 separate units and the cost of rewiring the hangarettes--site vist |
| May be req. |
4. CLIN 0002 - If the 3-phase output voltage regulation is within the MIL-STD-704F requirements, please confirm that is acceptable.
| *Only, if it meets or exceeds the limits of MIL-STD-704F. Typically, |
| Less than 50 milliseconds with a 100% load change--Under/over voltage |
5. CLIN 0002 - Please provided further definition on the single phase voltage trip (item 14).
| *If one leg of voltage drops off-line or below 10% of 480 VAC; 200/115V |
| (input/output), the machine Automatically falls offline to prevent |
| damage to assets/aircraft. |
6. CLIN 0002 - If the converter is mobile, will a remote station still be required?
| *Converters are not intended to be mobile, they are to be stationary, |
| On 18" risers, and bolted to the ground. |
7. CLIN 0003 - If the converter in CLIN 0002 is mobile, do you actually need (32) 18" stands?
| *See question 5: Converters are not intended to be mobile, they |
| are to be stationary, on 18" risers, and bolted to the ground. |
8. CLIN 0004 - Can the cable hangers be attached to the converter or do they need to be separate (example, floor mounted)?
| *Ideally, cable hangars will be attached to the converter; however, if |
| Room and without obstructing walkways, they can be secured to the |
| Ground--separate from the converter. |
9. CLIN 0004 - With a quantity of 32 converters, should the cable hangers match the quantity?
| *If providing 90 KVA units and utilizing the 4 already built connection |
| Points in each of the 4 hangarettes, hangers would need to be included. |
| *A total of 34 hangarettes will require hangars or floor mounted reels to |
| Properly/safely store the output cable when not utilized. |
| *The extra 12 (totaling 46 hangars/reels) is from the past installation of |
| Converters that did not have them but required for proper storage. |
10. CLIN 0005 - Please define the output cable length.
*at least/minimum 60 feet long
11. CLIN 0006 - In order to provide an installation price a site visit would be needed and time allowed to contact a local licensed electrical contractors. Please confirm a site visit will be scheduled to assess the installation needs?
| *Please coordinate with Holloman AFB's Contracting Office. |
| Point of Contact: A1C Wilkins, Shawndae @ (575) 572-7155. |
12. CLIN 0008 - Please provide further definition of an explosion proof output cable required?
| *Would require 4 of these output cables for the set of hangarettes |
| That require the 90 KVA units. If only providing 45 KVA units, this |
| Requirement is not needed. The connecting point of the output |
| Cable in the already built/wired hangarette requires an adapter |
| To plug into it (explosion proof)--cable itself does not require |
| Specifications of being explosion proof.--Site Visit may be req. |
13. CLIN 0008 - Please confirm you need a 60" por 60' output cable.
*The output Cable requirement: Minimum of at least 60 FEET long.
