nta:
1. Tiv thaiv tub sab tub nyiag - tsis-metallic, uas tsis yog-conductive thiab uas tsis yog-sparking, muaj tsis muaj tus nqi ntawm recycling, kiag li daws tus tub sab muaj teeb meem.
2. High load peev xwm - fiberglass thiab unsaturated cob.
3. Dawb tsim-manhole npog tau tsim raws li cov kev cai ntawm cov neeg.
4. Ntev lub neej -Minimum lifespan ntawm manhole npog yog 30 xyoo free ntawm txij nkawm.
5. Zoo kaw -Nws yuav muab ntsia tau rau hermetically, thiab zoo tsis txhob lom gases xau tawm los ntawm cesspool. thiab tsis muaj suab nrov muaj kuab paug los yog thaws.
6. Zoo coj thiab corrosion kuj -manhole cover yuav tsis xeb vim hais tias nws muaj zoo coj thiab corrosion kuj.
7. High thiab tsawg kub kuj -Excellent insulator (los-40 ° C ~ 200 ° C)
8. Ntais nyhav thiab ntau kev sib tw price- tus luj ntawm puas manhole npog tshwj xeeb tshaj yog SMC manhole npog yog sib zog. Lub composite manhole npog yog ntau yooj yim rau thauj, nruab thiab kho.
Daim ntawv:
1. Electric hwj chim pipeline zoo; Post, telecommunication, kev sib txuas lus pipeline zoo;
2. Txoj kev teeb zoo, hluav taws kub tswj zoo, tag nrho cov hom ntawm valve zoo;
3. City dej, kua pipeline zoo; Thaum tshav kub kub nkag, roj zoo;
4. Anti-xeb project, qhib ditch; Nws zoo li raws li yuav ua raws li cov neeg muas zaub uas yuav tsum tau.
