Wooden Cable Drum Production

Logs, which are the raw materials of our products, are purchased through the forest products tenders opened by the state or through the sale of various other producers. Thanks to the high quality raw materials we attach great importance to, superior products are obtained.

The logs used in the production of the wooden cable reels, which is the Affiliated products of JYTOP, are primarily processed in the log cutting machine. Hundreds of m3 of logs are processed every day in these modern cutting machines. As a result of the processes, the timbers are obtained. Then, they are carefully stacked and left to dry in order to be used in reels suitable for their structures.

The material used for JRJ connector is the same as that used for cable manufacturing.

The cleanliness of JRJ fusion joint field operation is strictly controlled, and the production time is short

JRJ fusion joints are divided into straight joints and

DEFINITION

The material of the cold shrink cable termination and the joint is an elastomer (usually silicone rubber or ethylene propylene rubber).  After special processing, it is vulcanized and injection molded in a mold, the material is stretched and expanded in the radial direction, and finally supported by plastic spirals to become part of the cable accessories.

PROCESS PRINCIPLE

Cold shrink termination cables and joints have a shrinkage property that allows them to fit perfectly into the cable. Then, the ports are sealed with semiconductor self-adhesive tape, which can make the cold-shrinkable cable termination have better insulation performance and achieve the effect of being waterproof and moisture-proof.

ADVANTAGES OF JYTOP COLD SHRINK TERMINATION KITS

Easy to install: Cold shrink technology does not require heating and no other tools. Low construction cost, suitable for construction in small construction space.
2. Wide range of applications: Cold shrink termination and cable joints use a unique pre-expansion cable manufacturing process, suitable for a variety of power cable diameters, and strong compatibility.
3. Excellent performance: The cold shrink terminations and cable joints are made of high-quality silicone rubber material. It not only has excellent hydrophobic performance but also does not form conductive water film and has self-healing properties.

Our cable lugs work in conjunction with standard cable crimping tools and come with inspection holes to ensure the conductor has been fully inserted before crimping occurs. Lugs with a bell mouth ensure smooth transition from lug to cable, avoiding problems of chafing where the cable is subjected to vibration.

Our range of cable lugs covers cables with copper and aluminium conductors.

THE CABLE TERMINAL LUG IS A CRAFTED DESIGN AND JYTOP EXPERTS RECOMMEND CONSIDERING ITS USE IN THE FOLLOWING SITUATIONS.
1. The location of the wire due to commissioning, maintenance, and other factors, the need for frequent disassembly, and installation of the cable and wire. For example, if two wires, sometimes need to connect, and sometimes need to disconnect, then you can use the terminal lug to connect them, and it can be disconnected at any time. And do not have to solder them up or wind them together, very convenient and fast. The majority of the material of the terminal is copper and aluminum, according to the material of the inner core of the cable to choose the appropriate copper lugs connection, if the cable is a copper wire, the equipment contact surface is aluminum, then you need a copper and aluminum terminals to connect. JYTOP electrical product specifications are more comprehensive, the product is high purity purple copper, and the surface layer of thin, is beautiful and durable.

2. For an electrical box or circuit board, etc. As a whole, the need for electrical connection with other external circuits. PCB terminal blocks for use on the circuit board, in the event of a line failure, you can easily detect the wire. Avoid the time-consuming and laborious removal of the wires from the circuit board.

3. The number of wires to be connected at the same equipotential point is large. The terminal lug has holes at both ends to insert wires, and screws for fastening or loosening and is suitable for interconnecting a large number of wires. In the power industry, there are special terminal blocks, and terminal boxes, covered with terminal blocks, single-layer, double-layer, current, voltage, ordinary, breakable, etc.

4. Larger wire diameter, not convenient to connect with the screw terminal lug. Plug-in terminal block using crimp frame wiring, access to large wire diameter, and protect the wire is not easily damaged.

5. Larger current, need to increase the contact area of the electrical connection. TB series high current terminal blocks can meet the needs of a larger current connection.

6. multi-stranded wires need to be connected to the same terminal lug. Because the same terminal block has more than one jack, convenient wire access. Bolt-type splice tube connector can connect copper/aluminum / aluminum alloy cable. Mechanical splice, no crimping tools, and accompanying operator skills are required, only socket wrench or wrench. Tinned and oxidized surface.

The invention of the cable terminal lug has been nearly a century of time, from the earliest combination of terminal lugs to the current diverse plug-in type, direct welding type, fence type, spring type terminals, and even bare terminals. The cable connector field has formed a perfect electrical interface technology system. Its use scope also expanded to rail transportation, security lighting, elevator power control, medical equipment, and other fields, in a variety of situations. In view of the convenient installation and stable electrical performance of the terminal block, it is gradually getting more customers’ trust.
