Cold Shrink Tubing for LV Cable Splices, Repair, Protection & Insulation - 3M Cold Shrink Splice Kit 3M 8429-12 Cold Shrink Tubes 3M 3M 8429-12 Cold Shrink Tubes 32.2mm-67.8mm Diameters - 305mm Length 3M Cold Shrink Splices & Splicing Kits are designed using the unique cold shrink delivery system developed by 3M - cold shrink tubes are supplied pre-stretched on a removable core for efficiency and ease of installation. Cold shrink tubes provide a constant radial pressure and seal without adhesive allowing for cable or pipe expansion and contraction after installation - 3M Cold Shrink is simple and fast to install, no tools or "hot-working" required for use in potentially explosive and hazardous area atmospheres, including Zones 1 and Zones 2. 3M Cold Shrink Splice Tubes 8429-12 - Typical Applications Insulation and sealing of inline cable splices and electrical connectors Primary electrical insulation up to 1kV for cold shrink cable repairs Conduit and cable breakout sealing - moisture barrier Tubes available in EPDM rubber and silicone (Low Smoke & Fume LSF) Cold Shrink Tubes 3M : EPDM rubber cold shrink tubes provide cable sealing, protection and insulation for low voltage (LV) power cables up to 1000 volts. Tough EPDM 3M cold shrink rubber tubes are suitable for underground cable joints and direct burial. Resistant to acids and alkalis. Resistant to fungi, ozone and UV light to seal, protect and insulate outdoor cables. How ? 3M Cold Shrink tubes are open-ended, tubular rubber sleeves, which are factory expanded onto a removable core. The core is removed after the cold shrink tube has been positioned for installation over an inline connection, splice or cable lug, allowing the cold shrink tube to shrink and form a waterproof seal. Cold shrink tubes provide a quicker, safer and easier sealing solution for cables and pipes than heat shrink - no "hot-work" permit required for oil, gas and petrochemical site installations. T&D stock an extensive range of 3M Cold Shrink Tubes and Tubing. 3M Cold Shrink Tubes meet worldwide standards ANSI, IEEE, VDE, JCAA, REA and CSA.

- 1. Page 1 of 4 Cold Shrink EPDM Tubes Connector Insulators 8420 Series Data Sheet __________________________________________________________________________________ Product Description 3M Brand PST Cold Shrink Connector Insulators are a series of open-ended, tubular rubber sleeves, which are factory expanded and assembled onto a removable core. They are supplied for field installation in this pre-stretched condition. The core is removed after the tube has been positioned for installation over an in line connection, terminal lug, etc., allowing the tube to shrink and form a waterproof seal. The insulating tube is made of EPDM rubber, which contains no chlorides or sulphurs. Six diameter sizes will cover a range of 1000 volt cables, copper and aluminium conductors. PST features are: v Simple installation, requires only workman’s hands v Accommodates a wide range of cable sizes v No torches or heat required v Good thermal stability v Seals tight, retains its resiliency and pressure even after prolonged years of ageing and exposure v Excellent wet electrical properties v Improved tough rubber formulation to with stand rough backfilling v Waterproof. Meets water seal requirements of NEMA Pub. No. PP-C1 v Resists fungus v Resists acids and alkalis v Resists ozone and ultraviolet light Applications v Primary electrical insulation for all solid dielectric (rubber and plastic) insulated wire and cable splices rated to 1000 volts v Directly buriable or submersible v For indoor, outdoor, or overhead use v Physical protection and moisture sealing for high-voltage, air-insulated connectors and lugs such as spacer cable and lug connections to bus bar v Insulation of secondary splices copper or aluminium conductors v Relocation of service v Dig-in repairs v Sheath repairs v Insulation of inline conductor transition connectors (see Figure 1) 8426 PST Cold Shrink Connector Insulator 70mm2 Connector 120mm2 Figure 1 CABLE JOINTS, CABLE TERMINATIONS, CABLE GLANDS, CABLE CLEATS FEEDER PILLARS, FUSE LINKS, ARC FLASH, CABLE ROLLERS, CUT-OUTS __________________________________________________________________________________ _______ 3M UK PLC Electrical Products 3M Centre, Cain Road Bracknell, Berkshire RG12 8HT Telephone: 01344 858616 Fax: 01344 858758 3M Ireland 33KV CABLE JOINTS & CABLE TERMINATIONS 3M UK PLC 11KV Sales Office Sales Office FURSE EARTHING 3M House, Adelphi Centre www.cablejoints.co.uk PO Box 393 Dun Laoghaire, Co Dublin, Thorne and Derrick UK Ireland Bedford MK41 0YE Tel 0044 191 Telephone: 353 1 280 3555 490 1547 Fax 0044 191 477 5371 Telephone: 01234 229462 Fax: 353 1 280Tel 0044 117 977 4647 Fax 0044 117 9775582 Fax: 01234 229433 3509

Page 3 of 4 Cold Shrink EPDM Tubes Connector Insulators 8420 Series Data Sheet __________________________________________________________________________________ Specifications Product Splicing of all 1000 volts or less inline power cables from 6mm2 to 500mm2 shall be done in accordance with the instructions provided with 3M Brand PST Cold Shrink Connector Insulators. Engineering/Architectural The connector insulator must be capable of operation at emergency overload cable temperatures of 130°C. It must be usable without additional covering or adhesive, both indoors and outdoors, in overhead, direct buried or submersed applications, on cables rated up to 1000 volts. It must be applied without additional heat or flame and, when applied according to the manufacturer’s directions, but immediately energizable. It must not be adversely affected by moisture, mild acids or alkalis, ozone or ultraviolet light. It must be compatible with all rubber or plastic insulated 1000 volt cables. It must conform to the requirements of ANSI C119.1 1974, appropriate sections of Western Underground Guide 2.14 and UL 486D. It must have been accepted by the US Dept of Agriculture, Rural Electrification Administration, for both submersible and aerial application. Performance Tests The characteristic, which is vital to the performance of the PST is permanent set. Permanent set is defined as “the percentage of the original stretched deformation not recovered in a given period of time after the deforming force (core) has been removed”. Because the PST tube has not been allowed to return to its original ID by the cable, a live rubber force exists between the cable insulation and the PST tube. The 8420 series tubes are installed on the core at approximately 250% stretch. The permanent set test is done in the tension mode and reflects the elastic memory property of the material. Field experience combined with laboratory test data has shown that our EPDM PST/Cold Shrink™ compounds exhibit excellent long-term elastic memory characteristics. Moisture, Heat and Seal Tests 3M Brand Connector Insulators meet or exceed the test requirements of UL486D and ANSI C119.1. Test Sequence. 1. 24 hours in room temperature water (30cm deep). 2. Insulation resistance at dc (500 to 1000V), 1 minute. 3. Dielectric ac withstand, 1 minute at 2200V. 4. Heat at 90°C (±5°C) for 72 hours. 5. Flex test: 10 cycles for 90° right and 90° left. 6. Twist test: twist 15° clockwise and then 15° counter-clockwise from centre 5 times. 7. Water immersion as in Step 1. 8. Insulation resistance as in Step 2. 9. Cold temp. 4 hours at –18°C ± 5°C. Bend and twist per Steps 5. and 6. at temp. 10. Flex per Step 5. 11. Twist per Step 6. 12. Water immersion as in Step 1. 13. Insulation resistance as in Step 2. 14. Current cycle and water submersion test: a) Heat conductor with current to 90°C for 1 hour. b) De-energize. c) Plunge in 25°C (± 5°C) water within 3 minutes of Step b) for ½ hour minimum. d) Repeat Steps a), b) and c), 25 times. e) Measure insulation resistance per Step 2. f) Repeat Steps a), b) and c), 25 times.
