3. 阻燃，耐火電線電纜的特性和選用
Characteristics and selection of flame-retardant fire-resistant wire and cable
1, 阻燃電纜：flame-retardant wire and cable
阻燃電纜是指：在規(guī)定試驗(yàn)條件下，試樣被燃燒，在撤去試驗(yàn)火源后，火焰的蔓延僅在限定
的范圍內(nèi)，殘焰或殘灼在限定時間內(nèi)能自行熄滅的電線電纜。他的根本特質(zhì)是：在火災(zāi)的情
況下有可能被燒壞而不能運(yùn)行，但可以阻止火勢的蔓延。
Flame-retardant wires and cables means that under the specified test conditions, the sample us
burned, after the test fire source is moved, the flame is spread only within the limited range, and
the residual flame or wire self-extinguishes within a limited time. Its fundamental characteristic is
that it may be burnt out in the event of a fire and cannot operate, but it can prevent the spread
of fire.
阻燃電纜的分類
其中含鹵阻燃電線電纜的絕緣層，護(hù)套，外護(hù)層，和輔助材料（包帶及填充）全部或部分采
用含鹵的聚乙烯（PVC）阻燃材料，因而具有良好的阻燃特性。
The insulating layer, the sheath, the outer sheath and auxiliary material (wrapping tape and
filling ) of the halogen-containing flame-retardant wire and cable wholly or partially made of
halogen-containing PVC flame-retardant material, thus having good flame-retardant properties.
而無鹵低煙阻燃電線電纜的絕緣層，護(hù)套，外護(hù)層以及輔助材料（包帶及填充）全部或部分
采用不含鹵的交聯(lián)聚乙烯（XLPE）阻燃材料，不僅具有良好的阻燃特性，而且在電線電纜燃
燒時沒有鹵酸氣體放出，電線電纜。和含鹵阻燃電纜相比， 無鹵低煙阻燃電纜有低腐蝕，
低煙的優(yōu)點(diǎn)，但電性能及機(jī)械性能明顯降低，所以在進(jìn)行電纜敷設(shè)時，無鹵低煙阻燃電線電
纜應(yīng)較含鹵阻燃電線電纜有更大的彎曲半徑。
The halogen-free cross-linked polyethylene (XLPE) flame-retardant material is used in all or part
of the insulation layer, sheath, outer sheath and auxiliary rib material (wrapping tape and filling)
of halogen-free low-smoke XLPE flame-retardant wire and cable, so such wire and cable not only
have better flame-retardant properties, but also no halogen acid gas is emitted when the wire
and cable are burning, with small amount of smoke. Compared with halogen-containing
flame-retardant wire, halogen-free low smoke flame-retardant wire and cable have the
advantage of low corrosion and low smoke, but the electrical and mechanical properties are
reduced, so when the wire and cable are laid, halogen-free low-smoke flame-retardant wire and
cable should have a larger bending radius than halogen-containing flame-retardant wire and
cable.
2, 耐火電線電纜： fire-resistant wire and cable series
耐火電纜是指：在規(guī)定實(shí)驗(yàn)條件下，試樣在火焰中被燃燒，在一定時間內(nèi)仍保持正常運(yùn)行的
性能。
Fire-resistant wire and cable mean that: under the specified test conditions, the sample still can
maintain normal operation for a certain period of time when burning .
耐火電纜的結(jié)構(gòu)與普通電纜基本相同，不同之處在于耐火電纜在導(dǎo)體和絕緣之間增加耐火層，
耐火層由多層云母帶繞包而成。
The structure of the fire-resistant wire and cable is basically the same as that of the ordinary wire???????
and cable. The differences is that a refractory layer is added between the conductor and the
insulating layer, the refractory layer is wrapped by a multi-layer mic tape.
耐火電纜的分類：
耐火電纜的分類：
A 類耐火電線電纜能夠在 950℃-1000℃的火焰中和額定電壓下耐受燃燒至少 90 分鐘，而電
線電纜不被擊穿。
Class A fire-resistant wire and cable can withstand combustion for at least 90 minutes in
950℃-1000℃ flame and under the rated voltage, without breakdown in wire and cable.
B 類耐火電線電纜能夠在 750℃-800℃的火焰中和額定電壓下耐受燃燒至少 90 分鐘，而電線
電纜不被擊穿。
Class B fire-resistant wire and cable can withstand combustion for at least 90 minutes in
750℃-800℃ flame and under the rated voltage, without breakdown in wire and cable.
以上表格中所包含的無鹵低煙低毒環(huán)保型電纜都具有阻燃，低煙， 無鹵，低毒，不含鉛，
鎘等有害重金屬及無磷等特點(diǎn)，在火災(zāi)時對環(huán)境造成的危害小，符合人對生態(tài)及保護(hù)環(huán)境的
要求，是綠色環(huán)保型產(chǎn)品。
The halogen-free, low-smoke, environment-friendly wire and cable included in the above table
have no cadmium and other harmful heavy metals and phosphorus, and have little harm to the
environment during a fire. Therefore, it is an environmental product that can meet people’s
requirement for ecological and environmental protection.
