PATC / PAT-MPL / PATL-3MPS portable earths for switchgear and substations of 6–35 kV and above
Country: Spain · Model: PATC / PAT-MPL / PATL-3MPS
The PATC, PAT-MPL and PATL-3MPS kits per IEC 61230 short-circuit and earth busbars, bus connections and equipment terminals in switchgear, transformer substations and outdoor switchyards, and their clamps grip conductors from Ø 4 to Ø 70 mm and busbars up to 90 × 100 mm. They are used to prepare the workplace when 6–35 kV equipment or substations of 110 kV and above are taken out for repair at industrial enterprises and in power systems.

Description
Each kit consists of clamps of aluminium alloy or brass that are tightened with a screw through an insulating stick, copper cables in PVC insulation, a connector and parts for connecting to the earthing grid. Many kits have a three-way connector in a rubber housing. The MPU clamps in the PATC-MPU and PATCPF-MPU are made with a MPU/B bayonet shank or a Hex-12 hexagonal one in the MPU/H version, and take round conductors of Ø 4–35 mm, flat busbars up to 45 mm wide and fixed points of 20–25 mm. The phase cables of these kits are 0.75 m long with a cross-section of 25, 35 or 50 mm². The brass 5014H clamps of the PATC-5014H turn on conductors of Ø 5–25 mm to the required angle, so busbars can be reached in different positions. In the PATL-3MPS/9510 the three MPS clamps are supplemented by three TTS locking terminals with independent keys, and access to the earthing becomes controlled.
How to choose
The main thing when choosing is the shape and size of the connection point. For conductors of Ø 5–45 mm and flat busbars the PAT-MPL is enough, and the PATC-TMC with a wide opening takes conductors of Ø 10–70 mm, busbars up to 90 × 100 mm and inclined plates up to 50 × 120 mm. In tight cells the lighter PATC-MPLE with clamps for horizontal and vertical busbars is handier. For overhead lines separate PATL kits with automatic clamps are needed, and for LV panels the ECBT series with cables of 25–120 mm².

FAQ
For what short-circuit current is the PATL-3MPS/9510 kit rated?
With a 120 mm² copper cable the PATL-3MPS/9510 kit withstands a short-circuit current of 31.5 kA. It includes three MPS clamps and three TTS locking terminals.
Why is the earth cable in the PATC-MPLE thinner than the phase-to-phase links?
The short-circuit current between phases is higher than the current to earth, so the earthing cable is made with a smaller cross-section.
Which kit is connected to a busbar vertically?
The PP15 clamps of the PATC-PP15 kit are placed vertically, on conductors of Ø 8–14 mm and busbars up to 14 × 54 mm. This makes it easier to check the quality of contact.
By what parameter is the insulating stick chosen for a PATC earth?
The manufacturer advises choosing the stick by the nominal voltage of the installation. Therefore the sticks will be different for 6–35 kV switchgear and for 110 kV substations.
