ANACONDA TYPES NWC AND NN FLEXIBLE LIQUIITIIGHT WIRING CONDUITS INTRODUCTION This technical catalog describes and details Anaconda Metal Hose flexible nuclear liquidtight wiring conduits. The jacket materials have been sub-jected to an envircnmental test program based on the guidelines of IEEE Standards 323-1974 and 383-1974 to determine its suitability for service within the containment of nuclear power generating stations.

Design conditions for nuclear wiring applications preclude the use of

, standard PVC or polyethylene jacketed flexible liquidtight wiring conduits since these jacket materials will not withstand the thermal shock and LOCA conditions sssociated with applications within containment areas of nuclear powered generation facilities.

Thermal, radiation and LOCA environment exposure test results are of signi-ficant importance in relating the use of our jacket materials for flexible wiring conduit. Test results show that the jacket compounds performed satisfactorily.

In addition to thermal, radiation and LOCA testing, flame tests have been conducted. These tests were performed to ICEE 383-1974 using a vertical tray with a ribbon type burner. The conduit jacket is self-extinguishing and does not afterburn. The conduit jacket chars with flame exposure but does not drip from the conduit.

In conclusion, types NWC and N?W conduit are suitable for Class IE applica-tions as described in IEEE 383 and IE2 323. Testing shows that these jacket materials provide a viable jacket for liquidtight flexible electrical wiring conduits subjected to service conditions found in nuclear wiring applications within containment areas.

M This specification covers Anaconds types NWC and NPW Flexible Liquidtight Electrical Wiring Conduit for use in nuclear wiring in trade sizes 3/8" through 6". The conduit is suitable for use with acceptable standard liquidtight conduit fittings. The flexible metal core of the conduit meets the applicable requirenents of UL standard #360. Type NWC is manufactured in sizes 3/8" through 4"; Type NPW is manufactured in sizes 5" and 6".

II. CONSTRUCTION A. GENERAL The conduit shall consist of a spirally wound interlocked flexible steel core with a radiation resistant jacket. The I.D. and O.D.

will be in accordance with dimensions shown in Table I. The core, sizes 3/8" through 1-1/4", shall have a copper bonding strip wound into the core profile.

B. INNERCORE The innercore shall be made of continuously interlocked heavy zinc coated steel strip and the I.D. of the finished conduit shall be free from corrosion and deposits of zine salts. Zinc coating on strip shall be of sufficient thickness to pass two one-minute Preece Dip tests.

C. JACKET The jacket shall be black in color and be radiation resistant and have a minimum thickness in accordance with Table I. The outside of the extruded jacket shall have a smooth appearance. Manufac-turer's identification and the trade size shall be clearly printed on the jacket at intervals of approximately one foot. The jacket material must be tested and. meet the guidelines defined in IEEE'323-1974 and IEEE 383-1974.

D. LABELS Each coil of finished conduit shall have an identifying label which includes manufacturer's name, trademark and the date of manufacture.

CRUSH The finished conduit shall be subjected to a crushing load which shall be increased until the original overall diameter is reduced by 507.. When that point is reached, the test is complete and the

, crush load applied shall not be less than that listed in Table II.

i The me.: hod of applying the crush load is es follows:

A 14" length of conduit shall be rigidly supported for its full length on one side while the crush load is applied at a rate of .2" per minute to the opposite side through a 6" sq. x 3/4" thick steel block centered on the test sample.

B. TENSILE The conduit when tested as fou ows shall withstand a tensile load as listed in Table II without the convolution lock being broken. A 15" length with the jacket removed and with an appropriate test fitting soft soldered each end shall be placed in the jaws of a tensile machine. The tension shall be applied at a rate of 2" per minute until the specified load is reached at which time the machine shall be shut off and the test is complete. . .. ^

C. U BEND .

The finished conduit when. tested as follows shall withstand the U Bend load listed in Table II without the convolution lock being broken. A test sample of conduit shall be cut to a length approximately three times the inside bending diameter shown in Table I. The test sample shall be bent into an arc of 180 and the U Bend load shall be applied across the outside of the bend. Loading shall be applied at a rate of 10" per minute until the specified load is reached at which time the load shall be removed and the test is complete.
