OPGW Photoelectric Composite Optic Cable
The optical fiber is laid on the ground wire of the overhead high-voltage transmission line, and the optical fiber communication network is formed on the transmission line. This structure has the dual function of ground wire and communication, and is generally called OPGW optiese vesel kabel.
Optical fibers are resistant to electromagnetic interference and light weight, and can be installed on top of transmission line towers without considering the optimal installation location and electromagnetic corrosion. Dus, OPGW has the characteristics of high reliability, superior mechanical properties, and low cost. This technology is particularly useful and economical when laying or replacing existing ground wires.
Features of OPGW Optical Cable
- 110KV and above high-voltage lines. Large span (generally greater than 250M).
- It is easy to maintain, easy to solve the problem of crossover lines, and its mechanical properties can meet the needs of large-span lines.
- OPGW optic cable adopts metal armor, which has no effect on high pressure corrosion and aging.
- OPGW optic cable must be powered off during the construction process, and the power loss is large. OPGW should be used for new high-voltage lines above 110KV.
- In the performance index of OPGW, the larger the short-circuit current is, the more good conductors need to be used as armor, and the tensile strength is also reduced. In the case of a certain tensile strength, the short-circuit current capacity should be increased. Simply increasing the metal cross-sectional area results in an increase in cable diameter and cable weight, creating safety concerns for pylon strength.

OPLC foto-elektriese saamgestelde optiese veselkabel
Foto-elektriese saamgestelde kabel (OPLC) is to place the protected optical fiber unit in the power cable, which can be used in power systems with rated voltage of 0.6/1KV and below. Dit integreer optiese vesel, transmissie koperdraad, en koper seindraad. Breëband toegang, toerusting se kragverbruik, emergency signal transmission and other issues.
Daarby, dit kan ook volgens klantbehoeftes aangepas word. As gevolg van die diversiteit van toegangsmetodes en die kompleksiteit van die gebruiksomgewing, vervaardigers kan ook aanpas volgens klantvereistes, volgens verskillende spannings, verskillende veselkerne, en verskillende strukture om die veiligheid en betroubaarheid van die netwerk te verseker.
Features of OPLC Optic Fiber
- Koste-effektief, integrates optical fiberand power transmission and distribution cables, vermy sekondêre bedrading, en kan konstruksie effektief verminder, network construction and other costs.
- Van toepassing op 'n verskeidenheid besigheidstipes, sterk aanpasbaarheid, sterk skaalbaarheid, en wye produkaanpasbaarheid.
- Die optiese eenheid is versoenbaar met die langtermyn werkstemperatuur van die kragkabel.
- Dit het sterk meganiese eienskappe, soos slagweerstand en goeie drukweerstand, en het sterk omgewingsaanpasbaarheid.
