h d' } t SQNP i H&AI-7 ) I Page 3 of 19 Rev. 0 l 6.0 PROCEDURE A. General Installation information I Cleanliness is of great importance in the making of any splice. The splicer's hands should be clean, particularly when applying the tapes, I and every reasonable precaution should be taken to exclude dirt and moisture while the work is in process. In a hot environment, sweat bands around the splicer's wrists will I tend to prevent perspiration from accumulating on the hands. Use of sweat bands is recommended. I No cables will be spliced inside containment without EN DES approval. Splicing of Coax and Triax cables shall not be permitted for class IE cables. Cables in the 480-V and medium-voltage class shall not be spliced inside the cable spreading' room. No splicing of insulated cable shall be made in cable trays located in Category I structures, except in electrical manholes or handholes. I Elsewhere, splicing of Class IE cables within Category I structures shall be made in splice boxes or metal enclosures, and documented on cable pull cards. Splices shall be staggered to avoid physical build-I up in the box, enclosure, or tray where applicable. Cables shall be supported so that there is no mechanical load on the splice. Each spliced circuit shall have a permanent identification cable tag or marker with its unique designation as shown on the cable schedule or I pull card, installed adjacent to the completed splice as shown on standard drawing SD-E15.3.4. l Splicing of condue:. ors shall generally be accomplished by means of butt splices crimped onto the wires by means of appropriate tools. ficcause of differences between tools and terminals of the listed I manufacturers, it is important to follow closely the manufacturer's instructions applicable to the specific installation being made. j Terminals and splices of a company shall always be installed with l a tool purchased from or certified by that company to ensuce a care-fully controlled uniform pressure crimp. Splicing -of medium-voltage (5-15kV) power conductors shall be insulated I with 3M Company splicing kit in accordance with standard drawing SD-E12.5.3. Where waterproof splice is required use Raychess's WCSF type N material and install as shown in step B.4 of the above standard I drawing. .,4 Splicing of med-voltage power cables shall be allowed where the lengths of cable required exceed the length of the cable on the reel.

I Either noninsulated or self-insulated butt splices may be installed in systems of 600V or less and wire size No.10 AVG and smaller. Self-insulated butt splices within the primary containment shall be either Tefzel (Thomas and Betts Company) or Kynar (AMP Special Industries). The vinyl or nylon self-insulated fittings are intended for applications where. the total temperature of the conductor does not exceed 105'C (221*F). Splices of 600V or less, vire size No. 8 AWG and larger, and those of the noninsulated type for smaller wires shall be insulated with Ray-I chem Corporation WCSF-N splice covers and installed in accordance with the manufacturer's instructions using an electric heat gun (do not use torch with open flame) available from Raychem as the heat sourc E Unless otherwise noted on design drawings, cables with rubber or rubber-like (silicone) 125'C or more insulation, in systems of 600V or less, shall be spliced by one of the following procedures: a. Install noninsulated butt splice of appropriate size and build up / over exposed copper surfaces with 3M Company, Scotch 70 tape (t'emp-erature rating of 180*C) to a thickness equal to the original in-sulation. The use of Raychem's WCSF-N shall be used as a repisce- ) ment for the jacket material. l b. For splices in multiple-conductor cable, splice and insulate the 1 l single conductors in accordance with a. above. The use of Ray-chem's WCSF-N (section 2.2.3) chall be used as a replacement for the jacket material for the overall Jacket, and shall be installed as shown in Attachment 2. c. Install self-insulated butt splices for wire size No.10 AVG and smaller. Self-insulated butt splices shall be either Tefzel or Kynar. These self-insulated butt splices are intended for ap-plications where the total temperature of the conductor does not exceed 150'C (300*F), e.g., within primary containment. A d. All splice connections to motors or similar type lesds using lugs or ,I 4 butt sleeves (insulated and noninsulated) shall have the appropriate t size WCSF type Raychem sleeve placed over the splice. W_a boot is required on the multi conductor cable Jacket. This connection will ~ be treated as a termination rather than a splice. 7 The following list serves as a guide only to the splice types .d*, (attached) for the various penetrations:
