Foreword

GB/T 13849 "polyolefin insulation and polyolefin sheath local communication cable" is divided into five sections. --- Part 1. General; --- Part 2. copper core, solid or foam (foam skin) polyolefin insulation, unfilled, moisture barrier polyethylene sheathed local telecommunication cable; --- Part 3. Copper conductor, solid or foam (foam skin) polyolefin insulation, Filled, moisture barrier polyethylene sheathed local telecommunication cable; --- Part 4. copper conductor, solid polyolefin insulation (unfilled), self-supporting, moisture barrier polyethylene sheathed local communication cable; --- Part 5. Copper conductor, solid or foam (foam skin) polyolefin insulation, isolated (inner shield), moisture barrier polyethylene sheathed local Communication cables. This section GB/T 13849 Part 1. This section drafted in accordance with GB/T 1.1-2009 given rules. This Part replaces GB/T 13849.1-1993 "polyolefin insulation and polyolefin sheathed local telecommunication cables - Part 1. General requirements" Compared with GB/T 13849.1-1993, the main technical changes are as follows. --- Modify the "skin foam polyolefin insulation" is defined (see 3.4,1993 version 3.5); --- Increased conductor 0.7mm and 0.9mm sizes (see 5.1); --- The "connect the conductors should be acid-free silver alloy solder and flux brazing or welding or cold welding, tensile strength at connection No connection should not be lower than the adjacent tensile strength at 85% "in the" 85% "to" 90% "(see 5.2,1993 version 5.2); --- Increasing the solid high density polyethylene and polypropylene, solid "after air oven heat aging performance wound" test conditions and requirements, and The "cold-formed damage" to "low temperature winding test"; increase the effective length of the heat-shrinkable insulation test for the L = 200mm Provisions (see Table 1); --- The "arithmetic average of the stranding pitch of the finished cable to any line in the 3m length measured should not exceed 155mm." The "No more than 155mm" was changed to "not more than 150mm" (see Chapter 7 edition of 7.3,1993); --- The aluminum plastic composite tape from the nominal thickness "0.2mm" was changed to "not less than 0.15mm" (see the edition 13.2.1,1993 13.1.1); --- Increase in finished cable polyethylene sheath removed mechanical and physical properties of high density polyethylene and flame retardant material tensile Strength, elongation before and after aging, environmental stress cracking resistance requirements and heat shrinkage (see 13.3.4); --- Increasing the suspension wire requirements (see 13.5); --- Increasing the outer sheath 53 and 553, detailed provisions of the sheath 33 and Type 43, Type 23 and termite outer layer is loaded (see para. 14 chapter); --- Increased requirements for flame retardant cable structure (see Chapter 15); --- The main electrical performance on modified as follows (see Table 6). • increasing the conductor size 0.7mm, 0.9mm DC resistance, resistance unbalance, capacitance unbalance attenuation requirements; • Increased foam, foam skin polyolefin insulated cable attenuation index; • Modify the Working capacitance index (Table 6,1993 version of Table 7 No. 4); • The "sub-unit line between proximal all combinations of acoustic attenuation MS≥79" changed to between "sub-unit of the line for all combinations The proximal end of the acoustic attenuation MS≥77 "(Table 6,1993 Version 7.1 Table No. 7); • Added "dielectric strength test, the AC voltage can also be used, which VAC rms test voltage = VDC/2". --- Added "mechanical and physical properties and environmental performance of the cable". Fill water permeability of cable, cable filled trickle performance, low temperature Bending, combustion characteristics of self-supporting cable pull-off force and flame retardant cable requirements (see Table 8); --- Increased provisions on environmental performance (see Chapter 18); --- Revised provisions regarding test methods (see Chapter 20, Chapter 17 of the 1993 revision); --- Modify the main raw material requirements are as follows. • increase the insulation material properties shall comply with YD/T 760-1995, and to delete the corresponding appendix (see 6.1, 1993 version of Appendix L); • Increased filling compounds and water blocking, blocking yarn specific performance should be consistent with YD/T 839-2000 and YD/T 1115- Provisions of 2001 (see 8.2.3 and 14.1.6); • increase the performance of the double-sided tape and plastic composite aluminum-plastic composite tape should be consistent with YD/T 723.2-2007 and YD/T 723.3- 2007 provisions, and delete the corresponding appendix (see appendix 14.2.4,1993 version 13.2.4 and M); • increase the polyethylene sheath materials should be consistent with GB/T 15065-2009 provisions (see 13.3.1). --- Deleted the Chapter 20 provisions of three packs requirements (see Chapter 20 of the 1993 edition).
