We provide multiple solutions of cable to equipment, equipment to equipment connection, as well as reserved cable expansion interfaces, and insulation protectionfor manufacturers of high-voltage and medium voltage electrical equipment such as circuit breakers, instrument transformers, transformers, and fuses. We also provide various solutions for the testing of these devices and the testing after connecting cables.
Connection between medium-voltage cable and electrical equipment of circuit breaker, instrument transformers, transformers and fuses
The cable is connected with the outdoor overhead line or the terminal equipped with post insulator on the transformer. Indoor termination will be used in AIS to connect the incoming and outgoing lines of copper bars. In high altitude areas outdoor termination will also be used. | For transformer or other indoor equipment, the indoor termination will be used to connect cable to transformer inlet and outlet bushing, and copper bar inlet and outlet in the AIS. | When cable connected with switchgear, transformer, circuit breaker, fuse, transformer equipped with outer cone wiring bushings of EN50181 standard, we provide CJB -series products to realize perfect cable connection of 40.5kV and below voltage for A\B\C\D\E\F bushings, as well as the connection of surge arrester required by the system.The outer cone insulation protection cap is used for the sealing and insulation protection of the outer cone bushing of the equipment. | ||
We provide surge arresters that can be directly connected or extended after connecting cables for electrical equipment with outer cone bushing, so as to prevent sharp voltage rise and damage to electrical equipment in case of unexpected line fault. | Test solution for outer cone separable connector already installed on cable We provide test stick GCA CJ10-TB-630/ GCA CJB10/20/30-TB-630 for voltage testing of type C-bushing separable connectors that have been installed on outer cone equipment. CJB10-EB provides grounding solutions. | When cable is connected withswitchgear and transformer equipped with inner conebushingof standard EN50181, we provide CBN-series products to realize perfect cable connection for 40.5kV and below voltage. We also provide protection caps for sealing and live protection for GIS termination installed on cables, and voltage test sockets to test electrical performance of cables with inner cone plug-in termination. Insulation stop end is available for sealing and electrical protection of inner cone bushing in the equipment. Voltage transformer plug, instrument transformer transition plug and CBN35-PT-2 transformer plug matched with inner cone size 2# bushing are applicable to transformer manufacturers: Dalian No.1 Instrument Transformer, Siemens transformer, and RITZ transformer. |
Equipment Test
Test of equipment with outer cone bushing We provide outer cone test termination and test cables with different voltage levels for electrical performance test of equipment with outer cone bushing. | Test of equipment with inner cone bushing 1.The inner cone current test device can test high current for the switches, transformers and other equipment equipped with inner cone bushing 2.Voltage test cable 3.Current test cable (temperature rise, dynamic thermal stability, arcing test) 4.Current on-off test cable (on-off large current under high voltage) | |
Cabinet connection - inner cone insulating bushing busbar connection We providefully insulated, completely screened, and entirely protective solution with high safety, strong current capacity and stable operation for the GIS cabinet of medium voltage inner cone insulating bushing. 1.CBN20(10)-JM- Ⅱ 、CBN20(10)-JM-Ⅲ Series Busbar, busbar insulators, insulating headers provide sealing and electrical protection for busbar insulators. 2.CBN35-JM-Ⅲ(G) 3.CBN35-JM- Ⅵ(including type A、type B、type C、type D) | ||
Cabinet connection - outer cone insulating bushing busbar connectionCabinet connection between medium voltage C-GIS gas insulated switchgear is flexible and convenient because it can be connected at the upper end, lower end or side of the cabinet. We provide a professional cabinet connection to enable switchgear manufacturers to standardize mass production of medium voltage C-GIS on unit basis,quickly and flexibly combined so as to shorten the lead time and inventory cost. Size of busbar insulatingbushing of switchgear is compliant with standard EN50181. |
Insulation of switchgear busbar, transformer incoming and outgoing lines and other equipment
We provide insulation solutions for overhead lines, substation busbarand junction insulation, various outdoor switches, transformer incoming and outgoing lines. |
