MYUNGJIN JEONGWAN Co., Ltd.

Leading the way in construction electrical materials, MYUNGJIN JEONGWAN is committed to excellence.

Excellent Flexibility

Due to its outstanding flexibility, there is no need for bending tools or torch lamps, making piping work easy.
Convenient Transportation.

The product is rolled and lightweight, making it easy to transport and handle even in challenging site conditions.
Perfect Connection Fittings.

We are a KS-approved manufacturer producing a variety of perfect connection fittings such as connectors, couplings, cone sleeves, and end covers in a One-Touch method. Our conduits ensure perfect joint connections, not only with our own products but also with those from other manufacturers.
Determining the Conduit Size

The inner surface of the conduit is corrugated, reducing friction and facilitating cable insertion even in 90-degree bends or over 30m of piping.
Long Length of the Conduit.

The length of the conduit reduces the need for connections, saving on couplings and also minimizing loss, making it very economical.
Minimal Condensation.

There is less condensation compared to steel conduits, allowing for use in sub-zero temperatures.

The tolerance for the length of the conduit is +2%.
The weight is calculated with a specific gravity of 0.955, and the weight reduction of the pipe is less than 8%.
The cutting length of the conduit can be agreed upon between parties.
