Cell phone jammer has the built-in Lithium battery

This section of the MT 818 Part 3 of this section instead of MT 818.3-1999 Mine flame-retardant cable Module 1: Mine mobile class 3 flame-retardant flexible cables part of the rated voltage and below 0.66/1.14kV enhanced soft Shearer shielded monitor cable, the MT 818.1-200x part and common use. Compared with the MT 818.3-1999 this part of the main changes are as follows: - modify the cable structure, the original structure of the defects can not be measured transition resistance to change (see Figure 1);GPS   cell phone jammer      will not affect the answering of normal phone.  - corresponding increase in the rated voltage 1.9/3.3kV cable specifications (see Table 1); - increased conductor cores associated monitoring requirements (see 4.1.2,4.1.3); - modify insulation performance requirements, authority control wire core insulation material requirements (see 4.2 and the 1999 version of section 4.2 of this ); - modify the cable outer diameter range (see the 1999 version of Table 2 and Table 2 of this section, Table 3); - modify the cable shield is required (see the 1999 version of the 4.3 and 4.3 of this section); - Amendment insulation resistance values (see the 1999 edition of the Table 3 and Table 4 of this section); - modified to enhance layer structure and performance requirements (see the 1999 version of the 4.7 and 4.6 of this section); - modify the cable jacket material and performance requirements (see the 1999 version of the 4.5 and this section 4.5,4.7);GPS     cell phone jammer will shield the GPS signal.  - canceled finished cable anti-extrusion, impact resistance, bending test (see the 1999 version of Table 4); - an important test of cable fire performance method of single vertical burning test, load test in addition to burning as a type test, the increase in sample test (see Table 6). This in part by the China Coal Industry Association, Ministry of Science and Technology Development. This part of the coal industry, coal mine safety standards by the Technical Committee.
