Description of the relevant knowledge of the open-close current transformer

　　 1. The open-close current transformer uses a high-strength PVC shell with a fully cast bus-bar structure. The three rubber rings of the transformer directly clamped on the cable resist the cable as a whole.

　　2. The iron core of the transformer is made of high-quality silicon steel sheet. The secondary wires are evenly wound on the iron core. The open-close structure can be installed without cutting the cable.

　　3. The altitude of the installation site of the open-close current transformer should not exceed 3000m.

　　4. The additional input current is 0.01A-400A; the material of the iron core is ferrite; the number of opening and closing times is not less than 1000; its flame retardant characteristics meet UL94-VO.
