Low Loss Thermal Conductor(TACSR/AS)
High Conductivity Thermal Resistant Aluminum Alloy Conductor Aluminum-clad Steel Reinforced
Low Voltage Aerial Bundle Cable
Low-voltage overhead insulated cables are mainly used to transmit power from distribution transformers to the customer end (e.g. residential homes, small commercial facilities, etc.). The insulation requirements are also relatively low, and insulating materials such as polyvinyl chloride (PVC) can be used at a relatively low cost, while also providing sufficient insulation protection against leakage and short-circuiting of low-voltage lines. The laying requirements of low-voltage overhead cables are relatively flexible and the safety distance requirements are relatively small. In some residential areas and other places, it can be laid closer to the building or ground under the premise of ensuring safety according to the actual situation, in order to facilitate the supply of electricity to the user terminal.
Low Voltage Swithgear(ZTMNS)
KYN28A-12 series switchgear is a type of indoor metal-clad withdrawable medium-voltage switchgear equipment, widely applied in power plants, substations, industrial and mining enterprises, commercial buildings and other locations for power distribution and control purposes.
Medium Voltage Aerial Bundle Cable
Medium voltage overhead insulated cables are mainly used in medium voltage distribution lines of urban power grids to transport electrical energy from substations to individual distribution transformers. High-performance insulation materials, such as cross-linked polyethylene (XLPE), which have good electrical properties and thermal stability and can withstand high electric field strengths, are generally used. As MV cables usually cover large distances, they can be subjected to higher voltages and mechanical stresses, such as those caused by wind, ice cover and other natural factors. Therefore, cables require high mechanical strength, including tensile strength and flexural strength. The conductors of cables are generally made of high-strength copper or aluminium strands, and the manufacturing process ensures that the cables are tightly constructed to improve their overall mechanical properties.
Pin Insulator
The pin composite insulator consists of a steel cap, a steel foot, a core body, and a silicone rubber shed. It is widely used in overhead distribution lines in urban and rural areas and can effectively improve the insulation level and operation safety of the lines.
Power Cable-Building Wire
Building wire ensures indoor electrical wiring’s efficiency, which is made of copper/aluminum, insulated & screened, it excels in conductivity, insulation, and durability. Essential in lighting, outlets, power equipment, and low-voltage systems in homes, offices, and factories, it’s crucial in modern electrical systems. Selecting it requires considering specs, current capacity, insulation rating, and operating conditions for safety and stability.
PTK Joint Box
The cable joint box is used for the direct joint and branch joint of optical fiber optic cable.
Rod-type Suspension Composite Insulator
AC/DC rod-type suspension composite insulators consist of end fittings, core rods, silicone rubber sheds, and grading rings. They overcome the limitations of traditional glass and ceramic insulators in terms of pollution resistance, mechanical strength, weight, etc., and have become key components for ensuring the safety of power transmission in modern power systems.
Screened Armored Cable
Screened armored cable combines the advantages of screen and armor, It can not only resist interference and electromagnetic radiation, but also has the characteristics of durable and withstand external force.
Screened Armored Cable
The low voltage cable with both shielding and armoring not only has excellent anti-electromagnetic interference capability, but can also effectively prevent mechanical damage. It is suitable for places with relatively complex and harsh environments, such as factory workshops, mines, outdoor construction sites and other places. In these places, there may be many sources of electromagnetic interference, and at the same time, the cables are also prone to mechanical damage from external force. The armoring layer can protect the cables from physical damage, while the shielding layer can resist electromagnetic interference and ensure the normal transmission of electricity or signals.

ZTT MV underground power cables have excellent electrical properties, intended for use in power transmission and distribution substation systems with an industrial frequency rated voltage of 6-35kV, with special features on request like flame-retardant, water blocking, anti-termite, etc. This type of cables are generally laid indoors, in tunnels and cable trenches and other places where certain radial mechanical external force or tension may happen.
Screened Unarmored Cable
Screened unarmored cable is a special type of cable designed to protect the signal from interference while providing the necessary mechanical strength without the need for additional armor.

Screened Unarmored Cable
The low-voltage cable with shielding but without armoring has an additional shielding layer outside the insulation, which can effectively reduce external electromagnetic interference and ensure the stable transmission of signals. It is commonly used in places with certain requirements for electromagnetic interference, such as computer network cabling, data transmission systems and the power supply lines for some precision instruments. In these scenarios, external electromagnetic interference may affect signal quality, and the shielding layer can reduce interference and ensure the accuracy and stability of signal transmission.
SJD Joint Box
The cable joint box is used for the direct joint and branch joint of optical fiber optic cable.
Smooth aluminum sheathed cable
ZTT HV and EHV underground power cables have excellent electrical properties, intended for use in long-distance power transmission. Costumed with special features on request like flame-retardant, water blocking, anti-termite, etc. The smooth aluminum sheath is allowed having closer contact with buffer layer, whose thermal resistance has been greatly reduced. Carry more fault short-circuit current, and bear excellent conductivity, thus more reliable to our clients.
