Comewill, as a leading China manufacturer and supplier, provides LMZK-10 current transformer for you, which offers core advantages including a compact size, detachable core for easy installation, and high-precision measurement using imported silicon steel. It is specifically designed for 10kV compact switchgear.
This LMZK-10 current transformer has core advantages such as small size, light weight, switchable, and easy installation, and is widely suitable for the procurement needs of compact fully insulated ring network switchgear. It is particularly suitable for combining with remote terminal equipment such as RTU and FTU to form a sampling unit, providing a comprehensive solution and data support for the entire system. After procurement and installation, there is no need to modify the original wiring. It can be directly installed on the connected incoming and outgoing cables, making the operation simple and fast, significantly reducing the cost of engineering installation. At present, it has been widely used in compact fully insulated ring network switchgear series such as SafeRing/Plus, Uniswitch, RM6/SM6, SVS, GA/GE, FB, SS, etc., and is also suitable for the procurement and supporting needs of combined substations, cable distribution boxes and other equipment.
In terms of core materials and processes, LMZK-10 current transformer uses high-quality imported high permeability silicon steel sheets as magnetic materials, which have the characteristics of detachable iron cores and low magnetic circuit losses. The resin is vacuum cast inside a flame-retardant plastic shell, with excellent moisture resistance, stable performance, and no need for later maintenance, which meets the purchasing cost-effectiveness requirements for long-term use. During installation, clamp the two semi-circular rings onto the phase separated cable and secure them with clamps to blend seamlessly with the cable, creating a beautiful and coordinated appearance. The product is suitable for the procurement scenario of 10KV cables with specifications ranging from 35mm ² to 400mm ². The clamp is made of high-quality stainless steel material, which is sturdy and reliable. There is no eddy current generated during use, ensuring the safe operation of the equipment.
The power factor on the load side needs to meet COS φ=0.8 (exhibiting hysteresis characteristics).
The rated secondary current can be selected from 5A or 1A specifications to meet the needs of different power systems.
Environmental temperature range: The lower limit is -5 ℃, the upper limit is 40 ℃, and the daily average temperature shall not exceed 30 ℃.
The rated operating frequency supports two common standards: 50Hz or 60Hz.
The installation altitude of the equipment should be controlled at 1000 meters or below.
The pollution level meets the Level II standard and is suitable for conventional industrial environments.
The production and inspection of the product strictly follow the national standards GB20840.1 and GB20840.2.
