INDIUM PHOSPHIDE (InP) WAFERS are semiconductor materials made of indium phosphide, a compound semiconductor that is widely used in high-frequency and optoelectronic applications. Due to its efficient electron mobility and direct bandgap properties, InP is favored for devices such as:
High-speed electronics
Laser diodes
Photodetectors
Telecommunications applications, including optical fiber communication
We offer the following InP Wafers:
Undoped InP Wafers: These are pure InP with no intentional doping, used in various applications where intrinsic properties are required.
N-type InP Wafers: Doped with donor impurities (such as tellurium) to increase electron concentration, useful in transistors and high-speed electronics.
P-type InP Wafers: Doped with acceptor impurities (such as zinc) to create holes in the semiconductor, used in light-emitting devices and other optoelectronics.
InP Substrates: Used as a base for growing other semiconductor materials in heterostructures for various applications.
InP Membrane Wafers: Thin layers of InP used for specific applications, including applications in flexible electronics and advanced photonic devices.
InP-based Quantum Dot Wafers: Engineered to create quantum dots that can be used in photonic and optoelectronic devices for enhanced performance.
Vacuum circuit breaker serves in the power system of 10kv and three-phase ac 50hz to function as switching different kinds of loads needing frequent operation, and can protect and control electric equipment in the industrial & mineral enterprise, power plant and substation as well. It can coordinate with the kyn28a-12(gzs1) middle-arranged manual-driven switchgear or xgn- stantionary switchger as well.

VN3-12E indoor medium-voltage AC vacuum circuit breaker is a newest product designed by our company which is applicable to 3-phases AC50Hz, 12kV indoor switch systems. The product is with characteristics of smaller volume, reliable insulation, no pollution, long time free maintenance and so on. It is produced with standardized circuit breaker assembly line and has good performance and perfect quality.
1. Equipped with modularized operating mechanism which make the maintenance and the replacing are more convenient. The replace of module do not affect the dynamic capability and also shorten the power-off duration.
2. The interrupter and primary circuit are sealed in the epoxy resin, which makes the circuit breaker is more reliable
3. The pole using convected and ventilated technique and lower resistance vacuum circuit breaker limit the temperature rising because of circuit breaker working for a long time and also reduce the power loss.
4. The operating mechanism is designed uniquely and avoids the moving contact over-rebounding when the circuit breaker is opened and prolong the vacuum interrupter mechanical life.
5. Past the type test according to the national standards such as GB, DL, international standards of IEC, CEI, DIN, VDE and other major industrialized countries.
VN2-24 indoor high voltage AC vacuum circuit breaker is a new designed our which is applicable to air-insulated indoor switch system. The whole structure is assembled with the switch body and operating mechanism. It is produced with standardized circuit breaker assembly line and has good performance and perfect quality.
1. Have a wide range with rated current from 630a to 3150a and rated short-circuit breaking current from 20ka to 31.5ka. The mechanical life can be up to 20000 cycles.
2. Be intended for indoor installation in air-insulated switchgear and have fixed version or withdraw able version.
3. Have perfect switching-capacity which can handle any condition arising from switching of equipments and components under normal operating or fault conditions particularly short-circuit and over-load.
4. Adopt coopers vacuum interrupter which is smaller volume, lower resistance, longer lifetime, better atmosphered technique, more perfect insulation and higher breaking capacity.
5. Be with more perfect external insulation because of the vacuum interrupter and main circuit being cast in epoxy resin poles.
6. Comply with stipulations defined in standards of gb, gl, iec, cei, din, vde and other major industrialized countries.
