Standard 1.It is manufactured according to Q/75230256-2.4(refer to BS 5308)Standard.2. The flame-retardant cables comply with the requirements of GB/T19216(IEC60331) Standard.2.The low-smoke low-halogen cable is also comply with the requirements of GB/T17650(IEC60754).GB/T17651(IEC61034) Standards.3.The low-smoke halogen-free cable is also comply with the requirements of GB/T17650(IEC60754).GB/T17651(IEC61034) Standards.Application ScopeIt is widely used for signal transmitting and controlling of the enterprise and scientific department in the field of energy,metallurgy and petroleum and chemical industry and so on, which have the requirement of flame-proof fire-fightiny.Characteristics of ProductCharacteristics of Product1.Rated voltage(U0/U):300/500V2.The Max.long-term permissible operating temperature of conductor of PVC insulated cable is 700C 900C 1050C(according to the grade of heat-proof after the type)3.The Min permissible laying temperature: 00C for PVC or HFPO sheathed cable:-200C for PE4.The operating capacitance between shielded pair(1kHz): no more than 100pF/m5.The capacitance unbalance between groups is not more than 300pF, when the cable is 250m in length, the test frequency is 1kHz.6. The permissible bending radius is recommended: Not less than 12 times of the outer diameter of the cable for which has armour or wrapped. Not less than 6 times of the outer diameter of the others.7.Bunching flame-retardant cable can pass the test according to GB/T18380-3(IEC60332-3).
