Subsea Electrical Cables
Subsea Electrical Cables are electrical wires wrapped in insulating and waterproof materials and laid underwater on the seabed and in rivers for the transmission of electricity or communications. Submarine cables are used for offshore wind power, aflandige boorplatforms, island grid interconnections, land island interconnections and other offshore projects to provide communication and power transmission.
VERI Submarine Power Cables has been researching the production of subsea electric cables for many years. Whether it is from environmental exploration of the seabed, marine physical surveys or case studies of large projects around the world. We also utilize advanced cable design, manufacturing and installation methods. Our subsea electric cables are guaranteed for excellent water resistance and longevity.
Subsea Electrical Cable Products Model
XLPE Insulated Submarine Cable
XLPE insulated subsea power cable has several advantages over paper-insulated and PVC-insulated cable. It has high electric strength, mechanical strength, high-aging resistance, environmental metal stress resisting anti-chemical cross, and it is a simple construction, using convenient and higher operating of long term temperature. It can be laid with no drop restriction.
Aansoeke: These subsea power cables are suitable for fixed installations in the offshore range, such as distribution networks or industrial installations. Such as plant engineering, industrial machinery, heating and air conditioning systems, krag stasies, ens.

Armored Signal Subsea Electrical Cable
Armored Subsea Electrical Cables are protected by steel armor on the outside of the cable core, the insulation and the inside of the outer sheath, and therefore have strong mechanical strength against external pressure and stretching. And also can also fight against the corrosion of various acidic substances on the seabed, stronger water-blocking properties. It has a strong resistance to all kinds of interference in signal and power transmission. Armored submarine cables of this construction are mainly used in mining, ondergronds, construction and submarine in the offshore range.

We Also Produce the Following Submarine Electric Cable
In submarine electric cable development so far, the structure has been designed to make a variety of exploration and experimentation, die hoofstruktuur sluit die volgende tipes in:
1. Impregnated Paper-Covered Submarine Cable
Geskik vir nie meer as 45kV WS en nie meer as 400kV GS-lyne nie. Huidiglik, dit word slegs op 'n waterdiepte van geïnstalleer 500 m of minder.
2. Oil-Filled Submarine Cable
Gebruik die metode van aanvullende swangerskap om die luggaping in die kabel uit te skakel. Wanneer die kabeltemperatuur styg, die imp regnant brei uit, die druk binne die kabel neem toe, en die demon regant vloei in die olievoorraadtenk. Wanneer die kabel afkoel, die swanger krimp, die druk binne die kabel neem af, and the pregnant in the oil supply tank flows into the cable again, voorkoming van luggapings. Dit kan dus gebruik word vir 110 kV en hoër lyne. Lê in waterdieptes tot 500 m.
3. Opblaasbaar (Pressure-Assisted) Duikboot kabel
Die gebruik van geïmpregneerde papiersakke met opblaaskabel oor oliegevulde kabel is meer geskik vir die langer ondersese kabelnetwerk. Maar as gevolg van die behoefte om onder diep water te werk met hoë lugdruk, verhoog dus die moeilikheid om die kabel en sy bykomstighede te ontwerp, algemeen beperk tot 'n waterdiepte van 300 m.
4. “Oil Pressure” Tube Submarine Cable
Slegs geskik vir 'n paar kilometer van die kabelstelsel, want die baie lang kabel om in die pyp te trek, is onderhewig aan groot meganiese beperkings.
5. Extruded Insulation XLPE EPR Cables
Geskik vir tot 200kV AC spanning. Etileenpropileenrubber is meer bestand teen dendritiese verskynsels en plaaslike lekkasie as poliëtileen, ondersese kabels meer effektief te laat funksioneer.
Prospects Of VERI Subsea Power Cables
Die kompleksiteit van die mariene omgewing van die ondersese kabelprojek stel hoë vereistes, onderwaterkabelingenieurswese is 'n erkende probleem in die wêreld, konstruksie probleme, en hoë instandhoudingskoste. And it was only a few companies in the world can lay and commission submarine high-voltage cables. The development of the subsea power cable market has been greatly restricted. Meer kwessies, maar meer oplossings vir die probleem.
Significance of the VERI Submarine Cable
In die toekoms, die toepassingsruimte van ondersese kabels sal wyer wees, it is important infrastructure equipment and is an important technical support for human beings to achieve the effective expansion of their activity area. Dit vervoer skoon see-energie na die vasteland, verlig die spanning van hulpbronne op die vasteland, en vervoer ook vastelandsenergie na die see, by te dra tot die ontwikkeling van die see-ekonomie. Veri Submarine Cable company firmly believes in this.
