Medium power transformers with a power range from 40 to 250 mva and a voltage of over 72.5 kv are used as network and generator step-up transformers. Medium power transformers are also widely used to step up power from on- and offshore-windparks, and may even be installed in offshore-substations. Bringing the energy safely to the consumer: a basic requirement applicable to all power transformers. However, every single one is unique designed according to individual factors such as voltage, power, climate, system topography, sound level and many more.
Small power transformers are distribution transformers from 5 to 40 mva with a maximum service voltage of 145 kv. They are used as network transformers in distribution networks. This type of transformer is normally a 3-phase application and designed according to national and international standards. The low-voltage windings should be designed as foil or layer windings. The high-voltage windings should use layer or disc execution, including transposed conductors. Normally, the cooling type of small power transformers is onan (oil-natural, air-natural) or onaf (oilnatural, air-forced). The tapping can be designed with no-load or on-load tap changers (nltc or oltc). Bringing the energy safely to the consumer: a basic requirement applicable to all power transformers. However, every single one is unique designed according to individual factors such as voltage, power, climate, system topography, sound level and many more.
Stranding sst opgw is cable product that produced by way of comprehensive stranding the acs wires and sst optical unit which replaced one or some of acs wires of traditional ground wire cable. It realized the function of optical fiber communication and has bigger diameter and more optical fiber compared with center sst opgw. Structure characteristics and application Big diameter and more optical fiber Big tensile strength and short-circuit current capacity, arrive the best balance of machanical and electrical properties One or more optical unit Best design of stranding, obtain secondary optical fiber extra length Strands plies can be two or three, the wire can be acs wire and/or the combination of aluminium alloy wire and aluminium wire.
The core of aluminum clad pbt tube opgw has structure of stranding pattern, when the multiple optical fiber pbt tubes are into cable, a layer of seamless aluminum tube will be clad on it which act as the protection tube of optical fiber metal and then stranding one or more aluminium clad steel wires or aluminum alloy wires outside it. It eliminates the worries about the electrochemical corrosion among different metals and has very high application value. Structure characteristics and application Seamless aluminum tube has uniform texture, consistent with the texture of the whole ground aluminum clad steel wire, no electrochemical corrosion Good fatigue resistance profit by consistence of texture and structure of the whole ground wire Optical fiber of aluminum tube opgw are exist in pbt tube, the core which is clad with a layer of thermal insulation material, with good thermal insulation effect and good protection effect of fiber optics, and short-circuit current has little influence to transmitting performance of fiber optics.
Center sst opgw cable is a kind of overhead grounding wire which take sst optical unit as the center, concentric stranding the acs wires at outer layer according to certain lay ratio. It is widely used in modern information electric power system. Structure characteristics and application Small diameter and light weight, small short-circuit current capacity Optical unit forms appropriate primary optical fiber extra length Characteristics of tension resistance, torsion resistance and side pressure resistance are not good enough Suitable for matching with gj-35 gj-50 gj-70.
