In P type TPM switchgears, a system is applied which allows the installation of straight cable bushings in air-insulated switchgear cubicles. The cable bending radius (depending on its outside diameter, according to PBUE) should be included in the tray depth for dry cables. Metering cubicle is not needed Sensors are small and weigh less than current instrument transformers (CT) and voltage transformers (VT) CTs and VTs weigh 18 -27 kg and sensors only 0.5 -2 kg Tests have been carried out to confirm that insulation performance can withstand system voltage even if the gas pressure drops to atmospheric pressure *2. Abstract: Although the contribution of SF6 (sulfur hexafluoride) emissions from gas insulated medium-voltage switchgear to man-made global warming is very small, an eco-efficient insulation gas will contribute to a reduction in the carbon footprint of the electricity grid. ZPUE, one of the most reliable medium voltage (MV) switchgear manufacturers, offers air or gas insulated, metal-enclosed solutions for diverse use. Cable type: single core with plastic sleeve, for example, YHAKXs, YHKX, XUHAKXs, XRUHKs, ... Notice: Straight cable bushings are used in the TPM, TPM P system switchgear in the transformer bay. Such units basically have a thirty-year minimum life span. The mechanical interlock assembly enables opening the cable compartment cover after closing the grounding switch. A fast grounding switch is an integral part of this device. Switchgear for lower voltages may be entirely enclosed within a building. The solid design of the TPM type switchgears assures reliability and resistance to adverse environmental conditions. Compact, gas insulated switchgear (SF6), metal casing ideal for indoor use in small container stations. The transformer bay is equipped with a stored energy release mechanism, which allows the circuit breaker to be opened after the reaction of the fuse-link striker. Gas-insulated switchgear (GIS) is very compact and therefore represents a space-saving alternative to classic air-insulated installations. There is an additional interlock in the transformer bay of the switch disconnector between the disconnector and the fuse-link striker, and between a grounding switch and the cover masking, which isolates the tubes. A burnt fuse-link is indicated on the front panel of the drive. RING MAIN UNIT DI-2. There is an interlock system between the switch disconnector (circuit breaker, disconnector) and the grounding switch, and between the grounding switch and the masking covers, which prevents incorrect switching procedures. The design of the switch-fuse unit compartment prevents its opening before the grounding switch has been closed.
