FDZ-10KV系列中壓預(yù)制分支電纜簡介
Introduction of FDZ-10KV Series Medium Voltage precast Branch Cable
我公司在繼低預(yù)制分支電纜之后,又成功的開發(fā)出 FDZ-10kv 系列中壓單芯愷裝預(yù)制分支電纜系產(chǎn)品,它的出現(xiàn)解決了原來中壓配電線路中
分支難、制作質(zhì)量差、故障多、制作環(huán)境要求高等一系列大難題。中壓預(yù)制分支電纜應(yīng)用于機(jī)場跑道、礦井等場所。
After the successful develipment of low voltage precadt branch cable we also developed FDZ-10 series medium voltage precast branch
cable series products.The product solves the series of problems of beingdiffcult to branch cable,poor operation quality, a lot of faults.high environmental requirements of operation and etc.
主要參數(shù) Main Parameter
1,額定電壓:10kv;
2,額定頻率:50Hz;
3、絕緣水平:a、工頻耐壓;45kv、1 miin; b、沖擊耐壓:75kv;
4、接觸電阻:R1:R2≤1.2,R1為接觸電阻,R2為等長的基線電阻。
1、Rated Coltage:10kv Ω;
2、Rated Frequency:50Hz;
3、Insulation Level:a.Power Frequency Withstand Voltage:45kv,1miin;b.Surge Withstand Voltage:75kv;
4、Contact Resistance:R1:R2≤1.2,R1 is contact resistance,and R2 is the same length of base line resistance.
主要優(yōu)點(diǎn) Main Advantages
1、絕緣采用高壓聚乙烯模壓成型、外護(hù)套為模型工藝,這些都能保證它們與原電纜的絕緣和護(hù)套粘合一起,使其防水、氣密,可直埋使用。
2、連接件采用鍍銀經(jīng) LYZ 工藝成型,使地主干線與分支線的接觸電阻很小(接近于基線電阻),而且長時(shí)間不會(huì)氧分。
3、連接件經(jīng) LYZ 工藝處理品為特殊形狀后,保證了分支連接體不但不受熱脹冷縮的影響,而隨連接的膨脹,分支線與主干線之間的抱緊力會(huì)增大,接觸電阻更小。
4、工廠化制作,解決了現(xiàn)場制作時(shí)的環(huán)境、工藝、人員素質(zhì)、工具等對(duì)質(zhì)量的影響,同時(shí)也大大節(jié)省了安裝時(shí)間。
5、工廠機(jī)械化生產(chǎn),保證了它性能更可靠、質(zhì)量更穩(wěn)定、外形更美觀。
1、Insulator of the product is made up of high.Voltage polytne and formed by mould predding.And the sheath adopts Mould technology,Thus,the insulator and sheath ca門be adhered with i門sulator and sheath of original cable to protect it from water water and make it air tight.lt can be laid directly in earth.
2、The connecting piece is plated with silver and formed by LYZ technology,therefore the contact resistance of ground main cable and branch cable is very little(is close to base line resistance)and the piece wont be oxidized in a long period.
3、After being processed into special shape by LYZ technology,the connection piece assures that the branch connector Expandswith connectiong piece instead of expanding with heat and contracting cold.Then,thenighteming Force between branch wire and main cable will be increased a門d the contact resista門ce will be smaller.
4、Being operated in factory,the product solves solves the quality problem of being effected by environment,technology,staff quality,tool,etc,during operation in field and meanwhile,it saves installation time greatly.
5、With factory mechanized production,the product performance is more reliable,the quality more steaby,and the appearance More beautiful.
